1. Liquid turbine flowmeter

Product Overview

Liquid turbine flowmeterBased on the principle of torque balance, it belongs to the speed type flow meter. Sensors have the characteristics of simple structure, lightweight, high accuracy, good repeatability, sensitive response, and easy installation, maintenance, and use. They can be matched with display instruments with special functions, and can also be used for quantitative control, over limit alarm, etc. They are widely used in industries such as petroleum, chemical, metallurgy, water supply, and papermaking, and are ideal instruments for flow measurement and energy conservation.Liquid turbine flow meters are classified by function: remote transmission type, integrated display type, low-power consumption type, and small quantity type.

II Product Features

• High precision,Generally, it can reach ±1%R, ±0.5%R,High precision type can reach ±0.2%R；
• Good repeatability, short-term repeatability can be achieved0.05%~0.2%,It is precisely because of its good repeatability that it can be obtained through regular calibration or online calibration The accuracy of * is the preferred flowmeter in trade settlement;
• Output pulse frequency signal, suitable for total measurement and computer connection, no zero drift, strong anti-interference ability;
• Original pulse frequency range（10Hz~1.5KHz）,Strong signal resolution.
• Wide range ratio, large range ratio can reach1:20；
• Compact and lightweight structure, easy installation and maintenance, and high circulation capacity;
• Suitable for high-voltage measurement, the sensor body does not need to be perforated, making it easy to make into a high-voltage instrument;
• Can be made into an insertion type, suitable for measuring large diameters, with low pressure loss, low price, can be removed without interruption, and easy installation and maintenance.
