Gas turbine meter scale for measuring principle and characteristics

Abstract: the measuring principle and characteristics of gas turbine meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Gas turbine flowmeter is a kind of common flow meter products, with high precision, good repeatability, simple structure, small volume, light weight, small pressure loss, long service life, simple operation, easy maintenance, etc. Today, we mainly introduce the gas vortex. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a gas turbine meter scale measuring principle and characteristics of the article details. Gas turbine flowmeter is a kind of common flow meter products, with high precision, good repeatability, simple structure, small volume, light weight, small pressure loss, long service life, simple operation, easy maintenance, etc. Today we will introduce the main measuring principle and characteristics of gas turbine flowmeter, hope you can help to you. Gas turbine flowmeter measurement principle of fluid flowing through the gas turbine flowmeter shell, because of the impeller blade and flow to a certain Angle, the fluid force makes the blade with rotational torque, to overcome the friction torque and fluid resistance, blade rotation speed stability after the moment balance, under certain conditions, the speed is proportional to the velocity of flow, because there are magnetic conductivity blade, it is in the signal detector ( Composed of * magnetic steel and coil) Of the magnetic field, rotating blade cutting lines, periodically changing coil magnetic flux, so that the coil ends induction electrical pulse signal, the signal after amplifier amplification in gas turbine flowmeter, plastic, form a certain amplitude of continuous rectangular pulse wave, can be spread far to display instrument, show the instantaneous flow or volume of the fluid. Within the scope of a certain flow, pulse frequency f with fluid flowing through the turbine flow sensor is directly proportional to the instantaneous flow rate Q, flow equation for: Q = 3600 * ( f/k) Type: f— — Pulse frequency [ 赫兹) k— — The instrument coefficient of sensor [ 1 / m3) Given by the check list. Q— — The instantaneous flow rate of fluid ( The working status) ( m3 / h) 3600 - — Conversion coefficient of each gas turbine flowmeter coefficient by the manufacturer to fill in in the verification certificate, k value into the matching according to gas turbine flowmeter, can show the instantaneous flow and cumulative total. Gas turbine flowmeter features small pressure loss, impeller has antiseptic function; To adopt advanced technology of ultra-low power consumption single chip microcomputer, the machine has strong function, low power consumption, superior performance. With nonlinear compensation function of intelligent traffic monitor precision. Accuracy of correction formula is better than that of & plusmn; 0. 02%. Instrument coefficient can be set up by the button online, and can be displayed on the LCD screen, LCD screen clear intuitive, reliability block using EEPROM to cumulative flow, instrument coefficient of power-fail protection, protection using high-performance MCU CPU time is more than 10 years, complete data acquisition, processing and display output of cumulative flow transient flow with display convenient man-machine interface implementation, in the form of standard 485 for data transmission. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
