Flow meter

1. The working theory is different Electromagnetic flowmeter working theory The electromagnetic flowmeter is a flowmeter that performs flow measurements according to Faraday’s law of electromagnetic induction. The advantage of the electromagnetic flowmeter is that the pressure loss is extremely small and the measurable flow range is large. The ratio of the maximum flow rate […]

Installation on field Mounting position Pipes must be fully filled with liquids. It is essential that pipes remain fully filled at all times, otherwise, flow rate indications may be affected, and measurement errors may be caused. Avoid air bubbles. If air bubbles enter a measurement pipe, flow rate indications may be affected and measurement errors

Two-wire PLUS Loop Powered Electromagnetic Flow Meter Ultra-low EMI switching power supply suits a wide range of power supply voltage and has good EMI resistance. It adopts 16-bit embedded microprocessor, which is fast, and high precision, uses low-frequency rectangular waves to exit, and programmable excitation frequency, which improves the stability of flow measurement and low

There are big differences in the performance of general-purpose electromagnetic flowmeter on the market. Some have high accuracy and many functions, and some have low accuracy and simple functions. The typical accuracy of a magnetic flowmeter is 0.5% of the measured value from 0.3 ft per sec to 33 ft per sec (0.1 to 10

Function The grounding ring is in direct contact with the medium through the grounding electrode and then grounded to the instrument flange through the grounding ring to achieve equipotential with the ground to eliminate interference. Grounding ring uses It is often not suitable to add a grounding ring on some occasions. For example, when measuring

There is no resistance element in the measuring tube of the electromagnetic flowmeter, so there is no pressure drop induced. The turndown ratio is 40:1, which means it can accurately measure a flow rate of as little as 1/40th of its maximum reading.

Magnetic flow meter Straight pipe： upstream≥5D, downstream≥3D. Insertion type entrance ≥10D, exit ≥5D Valve:  Flowmeter installed behind the valve, flow meter upstream ≥10, Downstream≥5D Front of right-angle turn： Upstream ≥10, Downstream≥5D Behind of right-angle turn： Upstream ≥10, Downstream≥5D Horizontal installation： The inner diameter of the pipe should be the same as the inner diameter of

Appearance aspect Flange thickness 1.Normally the non-standard flanges used in general electromagnetic flow meters, which are different from national standards. 2. Zero Instrument electromagnetic flow meter adopt national standards and are applicable to all the sites of the pipeline connection. Surface painting General electromagnetic flow meter uses one-time paint, so the product shell will be

Required lengths of straight pipe For optimum accuracy performance, it is required to provide sufficient inlet and outlet straight pipe runs. An equivalent to 3 diameters of straight pipe is required on the inlet side, and 2 diameters on the outlet side. There are no special requirements for standard concentric pipe reducers. See diagram 1

An electromagnetic flowmeter also called a mag-flow meter, is widely used for water and wastewater applications. Your fluid must exert a low-pressure drop and the appropriate needed liquid conductivity to use the instrument. It’s a durable device that is easy to maintain Mag-flow meters evolve with the current trends of technology of both sensors and
