Outline 

 XFTQ-B (C) gas turbine flowmeter is to draw a flow meter at home and abroad advanced technology optimized design of integrated pneumatics, fluid mechanics, electromagnetism and the theory developed by a new generation of high-precision, high reliability gas precision measuring instruments, with excellent low and high pressure metering performance, a variety of signal output mode and the low sensitivity of fluid disturbance, widely used in the measurement of natural gas, coal gas, liquefied petroleum gas, light hydrocarbon gas and other gases. 

 The series flowmeters using advanced ultra-low-power single-chip microcomputer technology to the development of the turbine flow sensor and display product count integration of new intelligent instrument, double LCD live display, with a compact body, intuitive readings, clear, high reliability, from the external power supply interference, anti-lightning, and low cost obvious advantages. Instrument with six meter factor correction, intelligent compensation instrument coefficient of nonlinear and can conduct on-site correction. The high-definition LCD display shows the instantaneous flow (four significant figures), and cumulative flow (8 significant digits, with a clear function). All valid data after power for 10 years is not lost. Kind of turbine flowmeters are explosion-proof products, proof grade: ExdIIBT6. 

 The type of turbine flow meter in accordance with the power supply, the availability of the remote signal output can be divided into XFTQ-□ B-type and XFTQ-□ C type. 

 □ XFTQ-type B: the power supply with 3.2V10AH lithium battery (which can run continuously for more than three years); signal output function. 

 XFTQ-□ C Type: Power supply 24VDC external power supply, two-wire current output 4-20mA standard signal, and may need depending on the site, increase the RS485 or HART communication.
