According to the site conditions how to select the right flowmeter
Date：2018-12-29
From：
Long run Binzhou electrical and mechanical summary of many years of customer telephone search records, find customers in the selection of flow meter of uncertain field construction for what kind of flowmeter, for everybody below summarizes several main points of selection of flow meter under.
General selection can be carried on from five aspects to consider, this five respects for instrument performance, fluid properties,installation conditions, environmental conditions and economic factors.
The 1 fluid properties:
Temperature, pressure, density, viscosity, chemical corrosion, abrasion, scaling, miscibility, phase transformation, electrical conductivity,thermal conductivity, specific heat capacity, speed of sound, isentropic exponent;
2 installation conditions:
Piping arrangement direction, flow direction, the test piece on the downstream side of the straight pipe length, caliber of pipeline, repairspace, power, grounding, auxiliary equipment ( filter, sensor ), such as the installation of;
The 3 instrument performance:
Accuracy, repeatability, linearity, range, flow range, the output signal characteristic, response time, pressure loss;
4, environmental conditions:
Ambient temperature, humidity, electromagnetic interference, security, explosion-proof, pipeline vibration;
5, economic factors:
Instrument purchase cost, installation cost, operation cost, check, repair costs, fees, service life of spare parts such as instrument.
Customers can according to the above five factors were selected, the primary type of information and prices were collected, for in-depth analysis of the conditions for the final target. Long run Binzhou electrical and mechanical friend calls welcome advice, my companyultrasonic flowmeter and reasonable price, products are exported to Portugal, Norway, India, Philippines, Europe and the United States, the Middle East and asia.
