【Products Introduction】

LWGY turbine flowmeter is manufactured by adopting foreign advanced technology, which is one of the ideal flowmeters for liquid measurement. It has the characteristics of simple structure, high accuracy, easy installation and maintenance, etc. The product is widely used in petroleum, chemical, metallurgy, water supply, paper making, environmental protection, food and other fields. This product is widely used in petroleum, chemical industry, metallurgy, water supply, papermaking, environmental protection, food and other fields, and reliably measures the volume flow of water, pure water, tap water, unadulterated sewage, diesel oil, gasoline and low-viscosity crude oil and other liquids. Used together with the display instrument with quantitative function, it can be used for automatic quantitative control, upper and lower limit alarm and other purposes.

【Product Selection】

1.LWGYA Turbine Flow Sensor

A type turbine flow sensor itself does not have on-site display function, only the flow signal in the form of three-wire voltage pulse remote transmission, power supply +12VDC or +24VDC, 250m. Power supply +12VDC or +24VDC, remote transmission distance 250 m. Instrument price is low, high integration, compact size, especially suitable for use with secondary display and other computer control systems.

2.LWGYB Turbine Flow Sensor

LWGYB type turbine flowmeter is based on the turbine flow sensor, adding a battery-powered on-site LCD display meter. The display table is developed using advanced ultra-low-power single-chip microcomputer technology, the sensor and the display table composed of a body-type turbine flowmeter. Compared with the traditional turbine flow sensor with secondary instrumentation measurement system, it has a small size, light weight, display readings intuitive, clear, high reliability and other obvious advantages. Head display mode single row 7-digit liquid crystal display, automatic switching display instantaneous flow and cumulative flow. Can also display the instantaneous flow or cumulative flow alone, low-power work: a lithium battery can be used continuously for more than 36 months, power-down protection instrument coefficients, the cumulative flow value to maintain ten nian not lost.

3.LWGYC Turbine Flow Sensor

LWGYC type turbine flow sensor is in the LWGYB type turbine flowmeter based on the addition of 4 ~ 20mA two-wire current transmission function, the instrument needs 24VDC power supply, can be displayed on-site and can be transmitted out of the remote transmission, especially suitable for use with the display instrument, industrial control machine, DCS and other computer control systems.
