Action

Close vents to high pressure and low pressure input ports. Close vents to wet legs in steam applications.

Open equalizer valve C.

Open valve A to make differential pressure zero (0) by applying same pressure to both sides of meter body.

Allow system to stabilize at full static pressure - zero differential.

Select DPInCal tab card and read input of applied DP (PV1) pressure in the selected engineering unit.

•If input reads 0% input, go to step 12.

•If input does not read 0% input,

-Click the Input option button.

-Click the Correct button to correct input to zero.

Select TempInCal tab card and read input of applied temperature (PV3) input in desired engineering unit. Verify that it is equivalent to process temperature.

Close equalizer valve C and open valve B.

In the FlowInCal tab card and read input Flow (PV4) signal in desired engineering unit. Verify that it is equivalent to calculated flow rate at operating conditions.

SMV Draft Range Start-up Procedure

Use the procedure in Table 24 to start-up an SMV 3000 transmitter model SMA110 and transmitters with small differential pressure spans.

Table 24 Start up Procedure for SMV Transmitter Model SMA110

Step Action

1Make sure that all valves on the three-valve manifold are closed. See Figure 26 for sample piping arrangement.

For installations without a three-valve manifold, connect a tube between the high pressure (HP) and low pressure (LP) input ports.

2Make sure the transmitter is attached to the mounting brackets but the bolts are not tightened completely; loosen if necessary.
