1. Overview of Liquid Turbine Flowmeter
Xindongxing Liquid Turbine Flowmeter is manufactured by our company with advanced foreign technology, and it is one of the ideal flowmeters for liquid measurement. It has the characteristics of simple structure, high measurement accuracy, long service life, simple operation and easy maintenance. This product is widely used in metallurgy, chemical industry, petroleum, urban construction, environmental protection, food and other fields to measure the volume flow of liquids such as water, tap water, diesel, gasoline, and low-viscosity crude oil with high precision.
2. The working principle of liquid turbine flowmeter
The turbine in the sensor rotates under the action of the fluid to change the magnetic field of the signal detector. Therefore, an alternating voltage is induced in the coil of the signal detector, which is amplified, filtered, and output by an amplifier to output a square wave signal. The frequency of this signal voltage is proportional to the speed of the impeller, that is, proportional to the flow (velocity) of the fluid.
Three, the meter type of liquid turbine flowmeter
A, on-site display type
This intelligent flowmeter is a new type of flowmeter display instrument designed with advanced single-chip microcomputer technology, and is matched with flow sensors (such as turbines, vortexes) that output pulse signals. Can display instantaneous flow and cumulative total. Cumulative flow: eight digits, instantaneous flow: six digits, which can show the change per liter. Display accuracy: ±1 display unit. Signal output: pulse output: external +12~+24VDC power supply Current output: 4~20mA external +24VDC power supply (two-wire system) built-in 2 3V lithium batteries in parallel for power supply. When the voltage is lower than 2.7V, there will be an undervoltage indication, explosion-proof type. Small signal removal function.
B, pulse output type
Working voltage: +12VDC or +24VDC two kinds (the customer chooses one kind of power supply before ordering). Signal transmission distance: less than 250 meters. Output signal: square wave signal amplitude: +12VDC power supply amplitude is about 10V+24VDC power supply amplitude is about 20V Installation: the amplifier and the turbine flow sensor are connected with M16×1.5 threads. After the turbine flow sensor is installed, screw the amplifier to On the turbine flow sensor, tighten the lock nut by hand until the amplifier feels to the end. Wiring: The pulse output type amplifier has three external leads, the red wire, the white wire and the shielded wire. The red wire is connected to the positive power source, the white wire is the pulse output and other displays or equipment are connected, and the shielding wire is grounded.
C, 4~20mA output type
Working voltage: external power supply +24VDC (two-wire system) output signal: 4-20mA or 1-5V, 4mA corresponds to zero flow of turbine flow sensor, 20mA paired turbine flow sensor flow, flow range see turbine flow sensor nameplate. Signal transmission distance: less than 250 meters. Installation: After the turbine flow sensor is installed, screw the amplifier to the turbine flow sensor connector (m16×1.5 thread), tighten the lock nut by hand until you feel the amplifier is at the bottom. Wiring: The external leads of the 4-20mA output amplifier are red and white wires. The red wire is the power wire, and the white wire is the signal wire.
D, split remote display type
Working voltage: external power supply 220VAC signal transmission distance: less than 250 meters, instantaneous four digits: cumulative total nine digits Can be connected to a computer.
