PCWL Series Turbine Flow Meter


Introduction

PCWL series turbine flow meter is a new generation kind of flow meter that absorbed the advanced technologies of flow meter at home and abroad, been optimized designed to have so many characteristics, such as simple structure, light weight, high precision, good reiteration, sensitive reaction, easy installation and using. It is widely used in the sealed pipelines which doesn’t have corrosion function on SS 1Cr18Ni9Ti, 2Cr13, corundum Al2O3, and cemented carbide and have no fiber, particle and so on, the liquid with viscosity less than 5*10-6m2/s under working temperature, if the viscosity of the liquid is more than 5*10-6m2/s, then the flow meter can be used after calibration. If it is equipped with other display devices with special functions, it can also do quantity control, excessive alarm and so on. It is really perfect in flow measurement and energy saving.


Features

1. High accuracy, usually reach ±1%R, ±5%R or even reach ±0.2%R for high-precision type;

2. Good repeatability, can reach 0.05%-0.2% in short term, if regular calibration or online calibration can get an extremely high accuracy, so it is preferred in trade;

3. Pulse signal output, suitable for total flow measurement and computer connection, no zero drift, strong anti-jamming capability;

4. High frequency signal (3-4kHz), strong signal resolution;

5. Wide range, middle and big diameter can reach 1:20, and small diameter can reach 1:10;

6. Compact structure, easy installation and maintenance, strong flow capacity.
