What kind of flowmeter is suitable for measuring water, which is accurate and less maintenance?
If you are not conductive liquid, vortex flowmeter depends on your flow, low flow rate of his uncertainty, and if the sewage cannot measure, did not say the above accuracy is so high, can reach 1% accuracy please, if people in 1: do not please you more than he will dead, 2: if it is not know to go to learn
If it is not sewage, and the pipe diameter is less than 100 mm:Glass rotor flowmeter (rotameter) the most affordable, a few hundred dollars, but only the instantaneous flow; turbine flowmeter, moderate precision, is a wheel in turn, may use one or two years to change a, the faster the change about the short time interval, there is also the highest accuracy or wear; gear flowmeter, similar to our water meter, but the price is relatively high, slightly cheaper than the electromagnetic flowmeter, large diameter may be expensive.
Well, if your water temperature is below 80 degrees, it's not pure water (not conductive), and if it's sewage mud, not a lot, it won't be deposited in the pipe. Electromagnetic flowmeter is absolutely preferred, mature technology, strong anti-interference, very few maintenance, and the price is moderate in the flowmeter. The accuracy is 0.5~1.0%
