Insertion Type Vortex Flow Meter Temperature Pressure Compensation with Modbus RS485
1. Introduction
LUGBML is based on vonkarman's vortex principle and uses pyelectron crystals as a test element. It is a new type of stress detection vortex street flow meter. It has the advantages of large range ratio, high precision, small pressure loss, good media versatility, pulse output and flow ratio, easy to connect with the computer, because the sensor probe and vortex generator are installed separately, high temperature-resistant die-electric crystals do not touch the instrument simple structure, good versatility, high stability. The LUGBML series of vortex street flow meter sensors can be used to detect and measure the flow of a wide range of gases, liquids and vapors. Can be used with my company ML6000 series vortex street flow meters. It can also be combined with computers and temperature, pressure, density sensors to form a high-precision mass flow or heat flow detection system.
2. Working Principle
The vortex flowmeter is a volume flowmeter that is researched and produced according to the Karman vortex principle to measure the volume flow of gas, steam or liquid, the volume flow of standard conditions or the mass flow. It is mainly used for flow measurement of industrial pipeline medium fluid, such as gas, liquid, steam and other media.
It is characterized by small pressure loss, large measuring range, and high accuracy. It is hardly affected by fluid density, pressure, temperature, viscosity and other parameters when measuring volume flow under working conditions. There are no movable mechanical parts, so the reliability is high and the maintenance is small. The instrument parameters can be stable for a long time. The vortex flowmeter adopts piezoelectric stress sensor, which has high reliability and can work in the working temperature range of -20℃～+250℃. It has analog standard signal and digital pulse signal output, which is easy to use with digital systems such as computers. It is a relatively advanced and ideal measuring instrument.
