Did you have used the water flowmeter?

Nov 20 , 2019

Shall I can introduce something about the International general model water flowmeter ? If yes, now I will begin. The brass digital water flow meter and salt water flow meter are our company’ s main product. But also we are one of the most professional supplier in our country. Because our products are of good quality and excellent price, they have won unanimous praise from people inside and outside the industry.

The international general model water flowmeter consists of two parts: sensor and converter. It is based on Faraday's law of electromagnetic induction and is used to measure the volume flow of conductive liquid with conductivity greater than 5μS/cm. It is an inductive instrument for measuring the volume flow of conductive medium. In addition to measuring the volume flow rate of common conductive liquid, it can also be used to measure the volume flow rate of strong corrosive liquid such as strong acid and strong alkali and uniform liquid-solid two-phase suspended liquid such as mud, ore pulp and paper pulp. It is widely used in industrial departments such as petroleum, chemical industry, metallurgy, textile, paper making, environmental protection, food and municipal management, water conservancy construction, river dredging and other fields of flow measurement. Digital quantity processing, strong anti-interference capability, reliable measurement, high precision, ultra-low EMI switching power supply with flow measurement range of 150: 1, wide applicable power supply voltage variation range and good EMI resistance. The 16-bit embedded microprocessor has fast operation speed, high precision, programmable frequency and low frequency rectangular wave excitation, which improves the stability of flow measurement and has low power consumption. There are no moving parts and no flowing parts in the pipeline, and there is almost no additional pressure loss in the measurement. High definition back lit LCD display, full Chinese menu operation, easy to use, simple to operate, easy to learn and understand. It has self-checking and self-judging functions.  The hourly total amount recording function records the total amount of flow in units of hours. It is suitable for time-sharing metering system. There are three integrators inside which can respectively display the forward cumulative amount, reverse cumulative amount and difference cumulative amount. There is always no power failure inside which can record 16 times of power failure time.

Insertion Flowmeter

The measuring principle of salt water flow meter is based on Faraday's law of electromagnetic induction. The measuring tube of Salt Water Flow Meter is a non-magnetic alloy short tube lined with insulating material. The two electrodes are fixed on the measuring tube through the tube wall along the tube diameter direction. The electrode tip is substantially flush with the inner surface of the liner. When the excitation coil is excited by two-wave pulses, a working magnetic field with a magnetic flux density of B will be generated in the direction perpendicular to the axis of the measuring tube. At this time, if the fluid with certain conductivity flows through the measuring tube. The electromotive force E is induced by cutting magnetic lines. The electromotive force E is proportional to the magnetic flux density B, and the product of the inner diameter D of the tube and the average flow velocity V is measured. The electromotive force E (flow signal) is detected by the electrode and sent to the converter through the cable.  After the converter amplifies the flow signal, it can display the fluid flow and output signals such as pulse and analog current for flow control and adjustment.
