Flow meter

Electromagnetic flowmeters, turbine flowmeters and vortex flowmeters are all commonly used flowmeters. They each have their own characteristics and usage environments. The following is their comparison: 1. Electromagnetic flowmeter: no mechanical moving parts, stable and accurate measurement, simple maintenance, but cannot measure non-conductive liquids Wide application range and large flow rate range Can measure liquids […]

The unstable output signal of the vortex flowmeter may be due to the following reasons: 1. Changes in the mass or pressure of the fluid: This may cause deviations in the measurement results of the flow meter. 2. Improper installation position: As mentioned above, if there is not a long enough straight pipe section or

Some common problems with instrument power supplies include unstable power supply, overheating of the power supply, too high or too low current, damaged power lines, etc. Here are some solutions to these problems: 1. The power supply is unstable: First check whether the power line is loose or damaged. You can also try to replace

An important feature of modern chemical production is the large-scale and highly automated production equipment. Automation is the basic condition and important guarantee for the safe operation, smooth operation and improvement of efficiency of production equipment. However, with the development of production and the improvement of automatic control level, the corrosion problem of chemical instruments

Several situations in which the measured liquid may cause malfunctions to the electromagnetic flowmeter may include: Poor liquid conductivity: The working principle of the electromagnetic flowmeter is to measure flow based on the conductivity of the liquid. If the conductivity of the liquid being measured is low, normal measurement may not be possible or the

Electromagnetic flowmeter is a flow measurement device designed based on Faraday’s law of electromagnetic induction. When using and debugging electromagnetic flowmeters, you can follow the following tips: 1. Perform zero point calibration: Zero-calibrate the electromagnetic flowmeter when the fluid in the flowmeter is stationary. This ensures accuracy during future use. 2. Pay attention to the

The principle of electromagnetic flowmeter is based on Faraday’s law of electromagnetic induction. The sensor is mainly composed of measuring tube, electrode, excitation coil, iron core and magnetic yoke shell. Electromagnetic flowmeter has many advantages and has become one of the first choice flowmeters for liquid medium measurement in industrial enterprises. The following introduces the

An electromagnetic flowmeter is an inductive instrument that measures the volume flow of conductive media in a pipe based on Faraday’s law of electromagnetic induction. The excitation coil in the pipe generates a magnetic field, and the measured medium flows through the pipe to cut magnetic lines of force, generating induced electromotive force on the

From the very beginning of electromagnetic flowmeter research, we have been faced with the thorny problem of how to overcome various interferences. Because of this, in the future research process of electromagnetic flowmeters, people have listed its anti-interference technology as the primary technical issue. The development of electromagnetic flowmeter excitation technology has greatly promoted the

Gas turbine flow meters are widely used in the measurement of natural gas, coal gas, liquefied gas, light hydrocarbon gas and other gases. They have excellent low-pressure and high-pressure measurement performance, multiple signal output modes and low sensitivity to fluid disturbance. When selecting a model, users should reasonably select the model and specifications of the
