Spiral Rotor Flowmeter (also called Duplex Rotor Flowmeter) belongs to the latest generation of volumetric flowmeter internationally, also known as screw flowmeter. It is a precision instrument used for measuring and controlling liquid flow rate in pipelines. Widely used in departments such as Petroleum, Chemical, Metallurgical, Electric Power, Transportation, Ships, Oil Depots, Docks, Tank Trucks, etc., it is particularly suitable for measuring flow rate of industrial liquids such as crude oil, refined oil, and light hydrocarbons. The flowmeter can indicate on site, read the code directly, and can be distributed with a communicator, output electrical pulse signals, and transmit them remotely to secondary instruments or computers to form automatic control, automatic detection, and data processing systems.

Has no pulsation, extremely low noise, high precision, and high reliability;

High precision (± 0.5%, maximum ± 0.2%), good repeatability;

Large range and low pressure loss;

Strong viscosity adaptability, capable of measuring high temperature and high viscosity liquids;

Stable and reliable performance;

Multiple counters, speed controllers, and external precision adjusters can be configured.
