HLY series turbine flow meter is a kind of intelligent integration by using the latest international digital integrated technology and according to the actual needs of domestic industrial automatic control research and development of a new generation of high quality intelligent instrument.Piezoelectric crystals as detecting element stress testing new type intelligent turbine flow meter.This instrument has the range than wide, high precision, small pressure loss, good medium generality, and the flow rate is proportional to the pulse output, current signal, the RS - 485 communication, and computer combination conveniently.This Instrument has the characteristics of simple structure, high universality and high stability, respectively, are two kinds of active, passive, passive type does not need outer power supply built-in 3.6 V batteries, battery life more than three years.The liquid crystal display meter, and instantaneous flow rate and flow accumulated, real-time temperature and pressure in real time.Intelligent turbine flow meter can through internal procedure, multi-point linear compensation for traffic signal, through the intelligent flow meter multi-point linear compensation, ensure accuracy of flow meter range segment at each point.

HLY series integrated turbine flow meter can be with our factory production of SXL general flow show that integrating instrument.Can also form a complete set with the computer of the quality of the high precision flow or heat flow detection measurement system.
