class c water flow meter in azerbaijan


Apr 25, 2017 · or as the en norm says, a water meter shall be designed and manufactured such that its errors of indication do not exceed the maximum permissible errors, mpes, as defined in class 1 and class 2. for the class 1, we have to look at the upper flow rate zone, which is q2 to q4, and 1%, so easy to remember-- class 1, 1%.
Class c & d the kent v100 (psm) is designed for the measurement of cold potable water and offer accuracy, long maintenance-free life and is tamper resistant. the meter operates on the volumetric rotary piston measurement principle and can achieve the highest levels of reading accuracy even at
The coriolis flow meters are in general very accurate, better than +/-0,1% with an turndown rate more than 100:1. the coriolis meter can also be used to measure the fluids density. open channel flowmeters
In most of the world water meters measure flow in cubic metres (m 3) or litres but in the usa and some other countries water meters are calibrated in cubic feet (ft. 3) or us gallons on a mechanical or electronic register. some electronic meter registers can display rate-of-flow in addition to total usage.
