Hot Sale Liquid Turbine Flowmeter With LCD
Hot sale liquid turbine flowmeter with LCD
Description:
A flowmeter for measuring with a turbine. It first converts the flow rate to the turbine speed, and then converts the speed into an electrical signal proportional to the flow rate. This flow meter is used to detect instantaneous flow and total accumulated flow, the output signal is frequency, easy to digitize
Features:
1.Can measure the flow is low, about vortex flowmeter 1/4, suitable for trade settlement
2.High accuracy, generally up to ± 1.5% R, ± 1.0% R
3.Good repeatability, short-term repeatability of up to 0.05% - 0.2%
4.Can achieve the integration of temperature, pressure real-time compensation, direct measurement of standard state flow
5.Pressure loss is small
6.Anti-vibration performance
