Common Type 1. Volumetric flowmeter, also known as fixed displacement flowmeter. It uses a mechanical measuring element to continuously divide the fluid into a single known volume fraction, measuring the fluid volume flow based on the number of successive repetitions of the measurement chamber and the number of discharges of the volumetric fluid.
2. Floater flowmeter, also known as rotameter, is a type of variable area flowmeter. In a vertical conical tube that expands from bottom to top, the gravity of a float with a circular cross-section is subjected to liquid power. This allows the float to rise and fall freely in the cone.
3. The differential flowmeter is a meter that calculates the flow rate based on the differential pressure generated by the flow detection device installed in the pipeline, the known fluid condition, and the size between the detection and the pipeline.
4. Vortex flowmeters place a non-streamlined vortex generator in the fluid. The fluid is alternately separated on both sides of the generator to release two strings of staggered vortices.
5. Turbine flowmeters, which are the main types of speed flowmeters, use a multi-blade rotor (turbine) to sense the average flow rate of the fluid and derive a flow or total meter.
6. Ultrasonic flowmeters, which measure the flow of the instrument by measuring the effect of fluid flow on the ultrasonic beam (or ultrasonic pulse).
7. Electromagnetic flowmeters and electromagnetic flowmeters are instruments that measure conductive liquids based on Faraday’s electromagnetic induction law. Electromagnetic flowmeter has a series of excellent characteristics, which can solve the problems that other flowmeters are not easy to apply, such as the measurement of dirty flow and corrosion flow.
8. Thermal flow meters, thermal flow meter sensors include two sensing elements, a speed sensor and a temperature sensor. They automatically compensate and correct for gas temperature changes. The electric heating part of the meter heats the speed sensor to a certain value higher than the working temperature, so that a constant temperature difference is formed between the speed sensor and the sensor that measures the working condition temperature. When maintaining the same temperature difference, the energy consumed by electric heating can also be said that the heat dissipation value is proportional to the mass flow rate of the flowing gas. It is suitable for the measurement of a single gas and a fixed proportion of multicomponent gas.
