ZWRY series intelligent electromagnetic flowmeter consists of two parts -- sensor and converter. It works based on the Faraday's law of electromagnetic induction. It is used to measure the volume flow rate of conductive liquid whose conductivity is greater than 5uS/cm. It is an inductive instrument for measuring the volume flow rate of conductive medium. In addition to measuring the volume flow rate of general conductive liquid, it can also be used to measure the volume flow rate of strongly corrosive liquids such as strong acid and alkali, and liquid-solid suspension liquids such as slurry, ore pulp and paper pulp. It is widely used for the flow measurement in petroleum, chemical, metallurgy, textile, paper, environmental protection, food and other industrial sectors, as well as municipal management, water conservancy construction, river dredging and other fields.
Vortex flowmeter is a volume flowmeter which measures the volume flow of gas, steam or liquid, the volume flow or mass flow under standard condition according to Karman's Vortex Principle. It can also be used as a flow transmitter in automatic control system.
I. Overview The liquid turbine flowmeter is a new generation of turbine flowmeter, which absorbs the advanced technology of flow meters from domestic and abroad and is optimized, with the characteristics of simple structure, lightweight, high precision, good reproducibility, sensitive reaction, easy installation, maintenance and use. It is widely used to measure closed pipes, for measuring liquids that has no corrosive effect with stainless steel 1Cr18Ni9Ti, 2Crl3, corundum A1203 and cemented carbide, without impurities such as fibers, granules, etc., and the kinematic viscosity is less than 5×10-6mm/s at working temperature. For liquids with kinematic viscosity greater than 5×10-6mm/s, the flowmeter can be used after calibration with the real liquid. If matched with display instruments with special functions, it can also carry out quantitative control, excessive alarm, etc. It is an ideal instrument for flow measurement and energy saving.
