Liquid Turbine Flow Meter Introduction

Liquid turbine flow meter is the main type of impeller type flow (velocity) meter. It is composed of sensors and conversion display. The sensor uses a multi-blade rotor to sense the average flow rate of the fluid, thereby deriving the flow or total amount. Liquid turbine flow meter is suitable for measuring liquids that are not corrosive to stainless steel 1Cr18Ni9Ti, 2Cr13 and corundum Al2O3 in closed pipelines and are free of impurities. For milk, soybean oil, edible oil, diesel, purified water.

Liquid Turbine Flow Meter Features


            

    • High accuracy: generally up to ±1%R, ±0.5%R, high precision type up to ±0.2%R.

    • Good repeatability, with short-term repeatability of 0.05% R to 0.2%R, which makes it the preferred flow

    • meter in trade settlements, precisely because of its good repeatability, such as frequent or on-line

    • calibration for high accuracy.

    • Output pulse frequency signal, suitable for total volume measurement and computer connection, no

    • zero drift, strong anti-interference ability.

    • Very high frequency signals (3-4 KHz) can be obtained, with strong signal separation rates.

    • Wide range, up to 1:20 for medium and large sizes and 1:10 for small sizes.

    • Compact and lightweight, easy to install and maintain, with high circulation capacity.

    • Suitable for high-pressure measurement, no holes are required on the meter body, and it is easy to

    • make a high-pressure meter

    • There are many types of special sensors, which can be designed according to the special needs of users,

    • such as low temperature type, two-way type, down hole type, special type for sand mixing;
