Smart gas Roots (waist wheel) flow meter Intelligent gas waist wheel (Roots) flowmeter is a new generation flowmeter that integrates flow, temperature, and pressure detection functions, and can automatically compensate for temperature and pressure. Gas is a compressible fluid, and its volume value is closely related to temperature and pressure. In order to unify standards for both parties, it is necessary to convert the actual volume into a standard volume under reference conditions (101.325 kPa 20°C). In order to achieve this purpose, the smart gas waist wheel flowmeter can accurately correct the volume of gas; it is an ideal instrument for gas measurement in urban gas, petroleum, chemical, electric power, metallurgy and other industries. more
TUF Series Portable Ultrasonic Flow Meter The TUF series ultrasonic flow meter utilizes the principle of low voltage and multiple pulsation time difference, adopts the high-precision and ultra-stable differential transmission of double-balanced signals and differential receiving digital detection technology to measure the acoustic wave transmission time in both the downstream and counter-current directions, and calculates the flow rate according to the time difference.It has the characteristics of good stability, small zero drift, high measuring accuracy and high anti-interference of measuring range over wide. more
LDB Intelligent Type Electromagnetic Flow Meter The LDB intelligent type electromagnetic flow meter consists of a sensor and a converter. It is based on Faraday's law of electromagnetic induction, which is used to measure the volume flow of conductive liquid with conductivity greater than 5μs/cm. It is an inductive meter for measuring the volume flow of conductive medium. In addition to measuring the volume flow of general conductive liquid, it can also be used to measure the volume flow of strong corrosive liquids such as strong acid and alkali and uniform liquid-solid two-phase suspension liquid such as slurry, pulp and paper pulp. more
