1. What are the types of flow meters?
The main types of flow meters are as follows:
1. Electromagnetic flow meters measure the flow rate of conductive media based on the principle of electromagnetic induction. Flow measurement is achieved by measuring the induced electromotive force of a fluid in a magnetic field. It has the characteristics of high measurement accuracy and wide applicability, and is suitable for flow measurement of most residual wax conductive liquids.
Secondly, vortex flowmeters use fluid dynamics principles to measure fluid flow.
. Calculate the flow rate by measuring the vortex phenomenon and pressure pulsation signal generated when the fluid passes through the sensor. Suitable for flow measurement of liquids and gases, it has the advantages of high measurement accuracy, simple and reliable structure, etc. Thirdly, ultrasonic flow meters measure fluid flow by measuring the time difference or phase shift of ultrasonic waves propagating in the fluid. It has the characteristics of non-contact measurement, high measurement accuracy, and wide applicability. Suitable for various fluid media, including liquids and gases, especially for flow rate measurement of corrosive fluids and solid-liquid two-phase fluids.Fourth, a mass flowmeter is an instrument that directly measures the mass flow rate of a fluid.
. Calculate the mass flow rate of a fluid by measuring the force or pressure loss generated by the fluid on the pipeline. It has the advantages of high measurement accuracy and the ability to measure various fluid media, and is widely used in flow measurement in industries such as chemical, petroleum, and food. 5. Other types of flow meters include orifice flow meters, n
2. What types of electromagnetic flow meters are classified according to the installation positions of sensors and converters?
Electromagnetic flow meters can be divided into integrated and split types according to the connection method of sensors and converters. The integrated bright ridge He type, also known as the on-site display type, directly displays instantaneous flow rate and cumulative flow rate.
; Split type refers to the installation of sensors on pipelines, and the converter, also known as the field display, is hung in a convenient and suitable place for you.3. Six commonly used classification methods for electromagnetic flow meters
The six commonly used classification methods for electromagnetic flow meters are as follows:
1. Classification by output signal connection and excitation (or power) connection system Four wire electromagnetic flow meters: The output signal line and the power blocking line (or the excitation wire between the flow sensor and the sensor) are composed of two sets of four wire systems with two wires each, which is the current mainstream sys
