![]() However, the mass flow controller is an instrument that can detect and control at the same time. The mass flow meter cannot control the flow, it can only detect the mass flow of liquid or gas, and output the flow value through analog voltage, current or serial communication. It is believed that it will show great potential in promoting flow measurement. The mass flow meter is a relatively accurate, fast, reliable, efficient, stable, and flexible flow measurement instrument, which will be more widely used in petroleum processing, the chemical industry, and other fields. Because the heat-sensitive measurement is used, the gas temperature and pressure changes will not affect the measurement result. The mass flow meter adopts the heat-sensitive measurement to measure the flow rate by the molecular mass taken away by the split molecules. ![]() In the same way, when the conductive fluid flows in the vertical direction in the magnetic field and cuts the magnetic induction force lines, it will also generate an induced electric potential on the electrodes on both sides of the pipe. The magnitude of the induced electric potential is proportional to the effective length of the conductor in the magnetic field and the speed at which the conductor moves in the magnetic field perpendicular to the direction of the magnetic field. When a conductor cuts the lines of force in a magnetic field, an induced electric potential will be generated in the conductor. But it cannot measure the flow of gas, steam, and pure water. It can measure the conductivity ≥5μs/cm Fluid flow of acid, alkali, salt solution, water, sewage, corrosive liquid and mud, mineral pulp, paper pulp, etc. The output signal is linear with the measured flow rate, and the accuracy is high. The applicable industrial pipe diameter range is wide, up to 3m. The ratio of the maximum flow rate to the minimum flow rate is generally above 40:1. The advantage of the electromagnetic flowmeter is that the pressure loss is extremely small and the measurable flow range is large. The electromagnetic flowmeter is a flowmeter that performs flow measurements according to Faraday’s law of electromagnetic induction. The working theory is different Electromagnetic flowmeter working theory You can select the best flowmeter for your flow measurement purpose (volume flow / mass flow / temperature / density), fluid type (liquid / gas / steam), and fluid condition (temperature / pressure / corrosive / slurry / viscosity).1. We have a wide lineup of flowmeter products with various measurement methods. With many industry firsts, Yokogawa continues to lead innovation in flow measurement. Yokogawa has more than 70 years experience in the development, design, and manufacture of various flow meter technologies. Available in glass and metal tubes, it can measure a wide range of fluids from gases to corrosive liquids. Our ROTAMETER has become synonymous with variable area type flowmeters. This simple measurement format has a long history as a field indicator. The measurement principle of the variable area type is that the position of the float in the tapered tube is proportional to the flow rate.
