Hydraulic flow meter

Description of hydraulic flowmeter:

Hydraulic flowmeter is a kind of speed meter used to measure low viscosity the volume of a gas in a closed pipe flow and total amount. In petroleum, chemical industry, metallurgy, urban gas network industries has wide use value.

Features of hydraulic flowmeter:

1. Measurable flow rate is low, which is about a quarter of the vortex flowmeter, suitable for trade settlement

2. High accuracy, generally up to + / - 1.5%, plus or minus 1.0% R R

3. Repeatability, short-term repeatability of up to 0.05% - 0.2%

4. Can realize the integration of real-time temperature and pressure compensation, direct measurement standard flow state

5. Low pressure loss

6.The strong vibration resistance
