Q&T - Model QTLL -Gas Roots Flow Meter
QTLL intelligent gas roots flow meter is a flow meter that integrates flow, pressure and temperature detection functions which could perform pressure, temperature and compression factor correction. It has a variety of structural forms and functional configurations to meet the different requirements of users. QTLL gas roots flow meter is widely used in the fields of urban gas and industrial gas flow measurement and detection, and could meet the user`s requirements for high-precision, high-reliability measurement or detection.
Gas roots flow meter is with high accuracy and good repeatability, it adopt high-precision imported dust-proof stainless steel special bearings which could ensure long service life. The intelligent integrated design can dynamically detect the temperature and pressure, and perform automatic compensation and compression factor correction. With advanced dual-power micro-power consumption technology, gas roots flow meter support battery working life more than 3years. Compared with precession vortex flow meter, gas turbine flow meter is with low pressure loss, low initiating flow and wider range ratio.
