Calibration and initialization of Wet leg impulse tube Rosemount 3051CD series LT

Calibration and Initialization of Impulse tube type Level Transmitter Rosemount 3051CD:

ww

Initial setting and calibration for water tank (here specific gravity =1)

Initial setting:

Take tap to tap measurement, for example if tap to tap measurement is 600mm then put

LRV=negative of tap to tap reading= -600mmWC    {negative value because after filling water on LP side the reading will be a negative value}

Put URV=0mmWC

Calibration of LT

here we are doing only zero checking; fill the impulse tube with water on both sides the transmitter reading should show zero reading i.e. -600mmWCor 0% level then the transmitter is O.K.

Initialization and calibration of tank having liquid of specific gravity other than water and impulse tube filled with liquid like that of glycol:

wwe.jpg

Initial setting:

take tap to tap measurement for e.g. if tap to tap measurement is 600mm and we are filling with glycol of 0.86 s.g. then

LRV=negative of tap to tap reading *s.g. of liquid inside impulse tube

=-600*0.86

=-516mmWC

 

and URV because of liquid inside vessel of s.g. 0.92is

URV=  LRV+ level(height) to be measured*s.g. of liquid inside vessel

= -516+(0.92*600)

=-516+552

=36 mm WC

Calibration (Zero checking):

fill the impulse line with glycol on both LP and HP side then the transmitter should show LRV=-516mmWC and 0% level

 

 

CROSS CHECKING OF  THE LRV AND URV IF THE TANK IS FILLED WITH WATER INSTEAD OF OTHER SPECIFIC GRAVITY

LRV= -600*1= -600mmWC

URV=LRV+HEIGHT OF LIQUID *SPECIFIC GRAVITY

= -600+(600*1)

= -600+600

= 0 mmWC

NOW NOTE THAT THIS IS THE SAME LRV & URV AS DERIVED ABOVE FOR WATER

 

N.B.  Calibration and initialization of DP type level follows a simple rule

LRV= level and property of liquid in impulse tube acting on LP side of LT

URV=LRV+level and property of liquid inside vessel acting on HP

 

Calibration and initialization of rosemount 3051CD capillary type level transmitter

ALIBRATION AND INITIAL SETTING OF CAPILLARY TYPE LEVEL TRANSMITTER:

 

UntitledInitilization:

If we are using capillary type level transmitter like Rosemount 3051CD series,

We can follow simple initial setting as follows:

  1. Install the level transmitter to the flanges provided i.e. LP side of the transmitter to top flange and HP side of the transmitter to the lower flange
  2. Keep the transmitter open to the atmosphere i.e. LP and HP side vented to atmosphere
  3. Power up the transmitter, the reading which is shown in the transmitter which will be generally a negative reading like for example -300 mm WC is the LRV value and note down this value
  4. Now the URV value is simply LP tap to HP tap (or centre to centre of the two capillary flanges ) measurement multiplied by specific gravity of the liquid inside vessel added to the LRV value For example if HP to LP distance is 600 mm and specific gravity of liquid inside vessel is 0.89 then URV is calculated as follows URV=LRV+(600*0.87)= -300+(522)=222mm WC
  5. After setting LRV and URV close the HP vent (drain) point and LP vent point.
  6. Line up both HP and LP side, the reading showing in the LT will be the process level in percentage.

 

Calibration Procedure:

 

  1. Take the necessary permit to work, take override if necessary
  2. Isolate the process i.e. close both LP and HP side and vent the both to atmosphere, Now the reading in LT should show 0% if not trim the transmitter
  3. Make an arrangement like that of a manometer, or a PVC transparent tube through which we can see water, and connect this to the drain(vent) point of the transmitter, measure the tap to tap point of LP and HP side and mark the corresponding 0%,25%,50%,75% and 100% in the PVC tube
  4. Now fill the water up to 25% and note the reading in LT it should show 25% and 8 mA. Similarly fill for 50% and reading should be 12mA,75% for 16 mA and 100% water in PVC tube for 20 mA
  5. Do span trim if necessary after filling 100% water, but if error is below 5%,it is advisable to not disturb the transmitter
  6. After calibration box up the transmitter, close the vent plugs and line up both LP and HP side

N.B: it is important to note that if initial setting is done for specific gravity 0.87 in transmitter and you are calibrating with water there will be some minor difference in the reading observed

Displacer type Level transmitter Fisher FIELDVUE™ DLC3010 Digital Level calibration

 

 CALIBRATION OF DISPLACER TYPE LT FISCHER DLC 3010

lt

Step 1:

Get Override from panel engineer and get PTW to work on the LT

Step 2:

Isolate the process from LT, i.e. isolate the three isolation point water, oil and gas points respectively and connect Hart communicator to the LT

Step 3:

Vent the gas from the upper bleed ring of the LT and drain the process from the chamber of level transmitter

Step 4:

Initial set up

Communicator Configure > Calibration > Primary > Guided Calibration (2-5-1-1) then enter the following values

Display unit>kg

Display value>mL

Display length unit > cm

Displacer weight> 3.200 kg

Displacer volume> 2686.1 mL

Displacer length> 290cm (not 380cm-default value- because here URV is 290)

Driver rod length> 20.00cm

Instrument mounting>left of displacer

TT material>NO5500

Level offset>0 cm

Desire action > Direct

Engineering unit of PV >cm

Calibration

If you only have a single fluid for calibration like water, run through Instrument Setup and verify all displacer data is correct. Set

Level Offset to 0. Select mode to Level application with direct action, and enter SG=1.0 (water) or actual SG of test fluid if different than 1.0. Proceed with Min/Max calibration; note that now the mode is in “LEVEL”.

Min/Max Calibration

The following procedure can be used to calibrate the sensor if the process condition can be changed to the equivalent of a completely dry and completely submerged displacer, and sight glass is available

Correct displacer information and the SG of the test fluid must be entered before performing this procedure.

Follow the prompts on the Field Communicator to calibrate the instrument and sensor.

  1. Set the control loop for manual control.
  2. Enter the specific gravity for the liquid in the system here water

s.g. = 1.00

  1. Follow hart instructions Configure>Calibration>Primary>Full calibration>Min/Max calibration
  2. Hart communicator will ask you whether the displacer is dry. Adjust the water level until the displacer is dry, that is, no water condition. Allow the output to settle, then acknowledge establishment of the minimum buoyancy condition to the system, accept this as the ‘Min’ condition. then enter min in hart communicator
  3. Hart communicator will then ask you to establish fully submerge the displacer with test fluid. Adjust the water level until the displacer is completely submerged in the liquid up to 290 cm. Allow the output to settle, then acknowledge establishment of the maximum buoyancy condition of the system Accept this as the ‘Max’ condition and then enter max in hart communicator.

The sensor torque rate is calibrated now, after this follow the step below to change to interface measurement

Run through Guided Setup and verify that all sensor data is correct.

Change the PV mode to “Interface”.

Set the Level Offset value to 0.00

Set the Specific Gravity of lower liquid to 1.09 and upper to .85 and continue to calibration check (not calibration here)

Calibration checks:

Since we are using interface measurement, we need to change the measurement mode to interface and check whether the calibration done is correct or not. Here it should be noted that this is cross checking for interface measurement and not the calibration as in min/max capturing

Mark in the chamber first point from zero level as 2900mm ie 100% (2900*1.00 i.e. s.g. of lower liquid here water 1.00)

Mark the second point as 2465m as 0% (2900*0.85 i.e. s.g. of upper liquid here crude 0.85) and we will perform calibration check between this 0 to 100 % range

Fill the chamber with water up to 2900 *1.00 =2900 mm and check for 100% interface level measurement, the transmitter should show 100% and 20 mA

Fill the chamber with water up to 2900 *0.85 =2465 mm and check for 100% interface level measurement, the transmitter should show 0% and 4 mA

Once the calibration and calibration check is over, put the vent plug and drain plug and isolate both vent and drain valve and open the gas isolation valve, followed by the oil isolation valve and then finally the water isolation valve and now the LT is taken into line and the reading now showing is the interface level measurement.

Allow the process for settle for half an hour and observe the LT reading

N.B.: here it should be noted that the If the digital level controller is not already coupled to the sensor, then it cannot be calibrated, so perform the following procedure to couple the digital level controller to the sensor.

Slide the access handle to the locked position to expose the access hole. Press on the back of the handle as shown in

Then slide the handle toward the front of the unit. Be sure the locking handle drops into the detent.

Reynold’s number

Reynolds number named after Osborne Reynolds (1842 – 1912), gives relation between inertial and viscous forces of fluid flow. If inertial forces (flow rate) are much bigger and Reynolds number is higher than critical, Re > 2320, turbulent fluid flow will occur and if viscous forces are big enough in compare to inertial (flow rate), Reynolds number is lower than critical, Re < 2320, laminar fluid flow character will occur.

For calculation of Reynolds number in closed pipe fluid flow mean velocity, fluid viscosity and internal pipe diameter should be known. Reynolds number is proportional to fluid flow mean velocity and pipe diameter and inversely proportional to fluid viscosity.

Reynolds number is calculated using following equation:

The Reynolds Number is given by the formula:

Where:
µ = the viscosity of the fluid,
V = the velocity of the object,
D = the diameter or length (basically the shape of the  object),
ρ=the density of the fluid.

With Reynolds number calculator you can analyze what makes fluid flow regime laminar and what is needed to force the fluid to flow in turbulent regime. For example – in pipes with very small internal diameter it is more likely to have laminar flow regime with small Reynolds number even for fluid with low viscosity. In fluid flow with temperature change flow regime can change from turbulent to laminar flow regime, as viscosity is changing depending on the fluid temperature.

Calculator can be used for all fluids and flow rates without any restriction. Calculator is applicable for fluid mixtures also, but viscosity of mixture must be entered.

 

 

 

Calibration Procedure of displacer type Level transmitter

Procedure:

*Ask panel man to put the controller in manual mode for control loop and to put it on MOS for ESD loop.
*Hook up HART Communicator and verify some parameters by refer to data sheet. Typical parameters are, tag number, PV, LRV and URV.
*Isolate the instrument from the process.
WARNING – If the process is hazardous, please ensure proper flushing is done to remove the entire hazard.
Remove isolation drain valve and open the vent flange
*Connect water pump to drain line and line up the reference tube
*Calculate the new measurement to get equivalent up trust force with S.G and length
*Mark on the chamber for reference calibration
*Hook up a multimeter in series with the signal to the DCS to measure current signal.
*Apply water level until 0% marking on chamber
*Multimeter should show 4mA
If not, do zero adjustment at transmitter using HART Communicator
Apply water level until 100% marking on chamber
*Multimeter should show 20mA
*If not, do span adjustment at transmitter using HART Communicator
*Verify the linearity by increasing and decreasing the pressure (0%,25%,50%,75%,100%,75%,50%,25% and 0%of range)
*After completion of the job ask panel operator to put loops back in normal mode or normalize the MOS

Example Calculation:
Low S.G=0.802
High S.G= 0.992
A= 810mm (measurement length)
0% = (A x Low S.G)
= (810 x 0.802)
= 649.42 mm
100% = (A x High S.G)
= (810 x 0.992)
= 803.52 mm
