1. What exactly is a turbine flowmeter?
The intelligent liquid turbine flowmeter is a new type of intelligent instrument developed using advanced ultra-low power single-chip microcomputer technology, which integrates turbine flow sensors and display integration. It adopts dual row LCD on-site display and has obvious advantages such as compact structure, intuitive and clear readings, high reliability, no external power interference, lightning resistance, and low cost. Turbine flowmeter is the main type of velocity flowmeter. When the measured fluid flows through the turbine flowmeter sensor, the impeller rotates under the action of the fluid, and its speed is proportional to the average flow velocity of the pipeline. At the same time, the blades periodically cut the magnetic field lines generated by the electromagnet, changing the magnetic flux of the coil. According to the principle of electromagnetic induction, a pulsating electric potential signal, namely an electric pulse signal, is induced in the coil. The frequency of this electric pulse signal is proportional to the flow rate of the measured fluid. A flow meter that uses a turbine for measurement. It first converts the flow rate into the rotational speed of the turbine, and then converts the rotational speed into an electrical signal proportional to the flow rate. This type of flowmeter is used to detect instantaneous flow and total cumulative flow, and its output signal is frequency, which is easy to digitize. The induction coil and permanent magnet in the picture are fixed together on the housing. When the ferromagnetic turbine blades pass through the magnet, the magnetic resistance of the magnetic circuit changes, thereby generating an induction sign
2. Sensor of turbine flowmeter
This type of turbine flow product itself does not have on-site display function, only transmits and outputs flow signals remotely.
. Flow signals can be divided into pulse signals or current signals (4-20mA); The instrument is inexpensive, highly integrated, and compact in size, making it particularly suitable for use with computer control systems such as secondary displays, PLCs, and DCS. This type of turbine flow product is divided into two types: basic type and explosion-proof type (ExdIIBT6). According to different output signals, this type of product can be divided into LWGY - □ N and LWGY - □ A LWGY - □ N sensors: powered by 12-24VDC, three wire pulse output, high level ≥ 8V, low level ≤ 0.8V; signal transmission distance ≤ 1000 meters; LWGY - □ A type transmitter: 24VDC power supply, two-wire 4-20mA output, signal transmission distance ≤ 1000.
