5.5Flowmeter zeroing
After the flowmeter has been fully installed, you must perform the zeroing procedure.
•To perform the zeroing procedure using the flowmeter zero button, see the following instructions.
•To use a HART Communicator for zeroing, see Chapter 6.
•To use ProLink II software for zeroing, see Chapter 7.
5.5.1Zeroing procedure
1.Prepare the flowmeter for zeroing:
a.Install the flowmeter according to the instructions in this manual.
b.Apply power to the meter, then allow it to warm up for at least 30 minutes.
c.Run the process fluid to be measured through the flowmeter until the meter temperature approximates the normal process operating temperature.
d.Ensure that the sensor is completely filled with fluid.
2.Close the shutoff valve downstream from the meter.
CAUTION
Flow through the flowmeter during flowmeter zeroing will result in an inaccurate zero setting.
Make sure fluid flow through the flowmeter is completely stopped during flowmeter zeroing.
