Product Introduction
Vapor vortex flowmeter is mainly used for flow measurement of steam medium fluid in industrial pipelines.Vapor Vortex flow meters are suitable for measuring gas flow because they can handle high pressure and high temperature applications and are highly variable. Different types of wet steam, saturated steam and superheated steam show different measurement characteristics. Vortex flowmeter can effectively adapt to this change.
Product Features
♦ On site display of temperature, pressure, instantaneous flow and cumulative flow.
♦ The vortex gas flow meter has unique time display and real-time data storage functions, which can ensure that internal data will not be lost and can be saved in any case.
♦ The power consumption of the whole machine is extremely low, and it can be powered by the built-in battery *. It is an ideal local display instrument without external power supply.
