Key points for selection of micro flowmeter

Micro flowmeter purchase, micro flow measurement in many industries are widely used, the smaller the flow, the more difficult to measure, this instrument manufacturers, is also a big challenge.In the measurement of small flow meter selection, there are the following points to note.

Installation conditions refer to gas flow direction, pipeline direction, upstream and downstream straight pipeline length, pipe diameter, spatial position and pipe fittings, which will affect the accurate operation, maintenance and service life of gas flowmeter.

Instrument performance refers to the precision, repeatability, linearity, range ratio, pressure loss, initial flow rate, output signal and response time of the instrument. The selection of flow rate timing should be carefully analyzed and compared with the above indicators, and the selection of the instrument that can meet the requirements of the flow rate of the measuring medium.

Accuracy grade and function according to the measurement requirements and the use of the occasion to select the accuracy grade of the instrument, to achieve economic and economic.

Economic factors refer to purchase, installation, maintenance, calibration and spare parts, which are also affected by the performance, reliability and life of gas flowmeter.

Fluid characteristics mainly refer to gas pressure, temperature, density, viscosity, compressibility, etc. Since the volume of gas varies with temperature and pressure, it should be considered whether to compensate or modify.
