QHT-LWGY Basic Liquid Turbine Flow Meter

I. Overview
QHT-LWGY Basic Liquid Turbine Flow MeterIt is a new type of intelligent instrument that integrates turbine flow sensor and display integration, developed using ultra-low power single-chip microcomputer technology. It adopts dual row LCD on-site display and has obvious advantages such as compact structure, intuitive and clear readings, high reliability, no external power interference, lightning resistance, and low cost. The instrument has three-point correction of instrument coefficient, intelligent compensation of instrument coefficient nonlinearity, and can be corrected on site. The high-definition LCD display simultaneously displays instantaneous flow rate (4 significant digits) and cumulative flow rate (8 significant digits, with reset function). Keep all valid data intact for 10 years after power failure. This type of turbine flowmeter is an explosion-proof product with an explosion-proof rating of ExdIIBT6.QHT-LWGY Basic Liquid Turbine Flow Meter

The basic liquid turbine flowmeter can be divided into LWGY - □ B type and LWGY - □ C type according to the power supply mode and whether it has remote signal output.
QHT-LWGY - □ B type: The power supply uses a 3.2V10AH lithium battery (which can operate continuously for more than 4 years); No signal output function.
QHT-LWGY - □ C type: The power supply adopts 24VDC external power supply, outputs 4-20mA standard two-wire current signal, and can add RS485 or HART communication according to different on-site needs.

2、 Product Features
1. High precision, generally up to ± 1% R, ± 0.5% R, and high-precision models up to ± 0.2% R;
2. Good repeatability, short-term repeatability can reach 0.05%~0.2%. It is precisely because of its good repeatability that it can achieve * accuracy through regular calibration or online calibration that flow meters are preferred for trade settlement;
