Kaifeng Instrument LWZ intelligent turbine flow meter is mostly used for the measurement and on site indication of the flow rate and total volume of the liquid and gas in enclosed industrial pipelines. It also can be used as the master meter to calibrate other flow meters, which are widely used in Petroleum, chemical, aviation, metallurgy and scientific research sectors.
LWZ type intelligent turbine flow meter consists of a LWG type turbine sensor and an intelligent converter. The 2 parts are connected by a stainless steel rod. There are 2 kinds of rods with different lengths, the stand rod will be used for fluid with the temperature between -20℃ ~ +55℃, and the longer rod for fluid with the temperature between -20℃ ~ +120℃.
l Advanced single-chip technology, powerful performance, high precision
l Laminated structure, easy to disassemble and maintain, free debugging
l Adopting micro-power technology
l Local indication of the total amount and instantaneous flow rate
l Output options for pulse signal and 4mA ~ 20mA analog signal
l Parameters can be set on site by the buttons
l Compact in structure, light in weight, intuitive to read and operate
l 5-section coefficient correction to ensure the accuracy
