Instructions for using the unit to manage the orifice flowmeter

The orifice flowmeter is a high-range differential pressure flow device that combines a standard orifice plate with a multi-parameter differential pressure transmitter (or differential pressure transmitter, temperature transmitter and pressure transmitter) to measure gas, The flow of steam, liquid and lead is widely used in process control and measurement in the fields of petroleum, chemical, metallurgy, electric power, heating, water supply and so on. The throttling device, also known as the differential pressure flowmeter, is composed of a single detecting piece (throttle piece) and a secondary device (differential pressure transmitter and flow rate display), which are widely used for flow measurement of gas, steam and liquid. The utility model has the advantages of simple structure, convenient maintenance and stable performance.
Use unit to manage the orifice flowmeter

1. Establish a flowmeter operation file, including the manufacturer, model, production date, installation location, pipe diameter, calibration time, etc. of the flowmeter to facilitate maintenance and management of the instrument.

3. Compare the test data with the previous test results, carefully analyze the research on the suspicious data, find out the possible causes, solve the problem in time, and make an analysis report on the flowmeter operation.

2. Strengthen the inspection inspection work and conduct regular test calibration. Two methods are mainly used. One is to compare the portable flowmeter with a relatively high precision with the orifice flowmeter. The other is to use a flowmeter checker to verify the flow converter and check each. The technical indicators are correct and the test data is archived.
