1、 Overview

The LWQ gas turbine flowmeter is a new intelligent instrument developed using advanced ultra-low power single-chip microcomputer technology, which integrates turbine flow sensors and display integration. 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.

Selection guide: When selecting, manufacturers should reasonably choose the model and specifications of flow meters based on the nominal pressure of the pipeline, medium, maximum pressure, medium temperature, medium composition (such as natural gas, various gases), flow range, and signal output requirements. To make the use of the flowmeter more accurate, the flow range of the flowmeter should be within the Qmax range of (20% to 80%), which is more appropriate.
