The CNM LWQ is a highly accurate flow meter, approved for custody transfer measurement, equipped with electronic pulse outputs and a mechanical counter. This document explains the dimensions, ranges, performance, calibration and outputs of the instrument. It details the installation, safety requirements and material
The CNM LWQ measures gas volume flowing through an annular passage in the meter. The flowing gas volume is totalized on a local mechanical counter. In addition, low or high frequency pulse signals are generated to infer the gas flow and volume.
The indicated gas volume is the actual volume flowing through the meter at the actual temperature and pressure. The LWQ is an economically priced meter with a good accuracy.
