Flow meter maintenance and service life

Fluid properties mainly refer to gas pressure, temperature, density, viscosity, compressibility, etc. Since the volume of gas changes with temperature and pressure, it should be considered whether to compensate and correct.
Instrument performance refers to the accuracy, repeatability, linearity, turndown ratio, pressure loss, initial flow rate, output signal and response time of the instrument. When selecting a flow meter, the above indicators should be carefully analyzed and compared, and the meter that can meet the flow requirements of the metering medium should be selected. meter.
The installation conditions refer to the gas flow direction, pipeline direction, upstream and downstream straight pipeline length, pipe diameter, space position and pipe fittings, etc., which will affect the accurate operation, maintenance and service life of the gas flowmeter.
Economic factors refer to purchase costs, installation costs, maintenance costs, calibration costs and spare parts, etc., which are also affected by the performance, reliability, and service life of the gas flowmeter.
Accuracy grades and functions Choose the accuracy grade of the instrument according to the measurement requirements and usage occasions to achieve economical results. For example, it is used in trade settlement, product handover and energy metering occasions,
