LWGK series IC card intelligent flow controllerThe gas turbine flowmeter sensor, CPU card flow compensation controller (hereinafter referred to as the controller), and card controlled valve are integrated by a single microprocessor to complete temperature, pressure, flow detection, volume correction, and prepaid control functions. It not only has all the advantages of a base meter and a correction instrument, but also solves the problem of asynchronous measurement and deduction in combination products. The product also uses CPU card and ESAM module, which can prevent network attacks, replication, ensure safe, reliable, and confidential use. The new generation flowmeter is an ideal industrial prepaid measuring instrument.
