1. 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. The intelligent integrated turbine flowmeter adopts advanced ultra-low power single-chip microcomputer technology to develop a turbine flow sensor and a new type of intelligent instrument material information grip meter that integrates display and calculation. It adopts a 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. The instrument has three-point correction of instrument coefficient, intelligent compensation of instrument coefficient nonlinearity, and can be corrected on site. The high-definition Chu LCD display simultaneously displays instantaneous flow (4 significant digits) and cumulative flow (8 significant digits, with a reset function). Keep all valid data intact for 10 years af

2. What are the applications of turbine flow meters in velocity flow meters? The rotational speed of the impeller is proportional to the flow rate, and the rotational speed of the vortex flowmeter impeller is proportional to the total amount of flow. The output of the turbine flowmeter is a frequency modulated signal, which not only improves the anti-interference ability of the detection circuit, but also simplifies the flow detection system. Its range ratio can reach 10:1, and the accuracy is within ± 0.2%. The time constant of a turbine flowmeter with small inertia and size can reach 0.01 seconds. The fluid flows through the sensor housing. Due to the angle between the blades of the impeller and the flow direction, the impulse of the fluid causes the blades to have a rotational torque. After overcoming the friction torque and fluid resistance, the blades rotate. After the torque is balanced, the speed is stable. Under certain conditions, the speed is proportional to the flow velocity. Due to the magnetic conductivity of the blades, they are in the magnetic field of the signal detector elec
