Working Principle
The Vortex Flow Meter operates on the Karman Vortex Shedding Principle. When a fluid passes through a bluff body installed in the flow path, alternating vortices are generated downstream. The frequency of these vortices is directly proportional to the flow velocity of the medium. The sensor detects these vortices and converts them into highly accurate flow measurements.
This proven technology ensures reliable performance for both volumetric and mass flow applications.
High-Precision Coriolis Mass Flow Meters
Unmatched Accuracy for Direct Mass Flow, Density, and Temperature Measurement
Overview
Engineered for demanding industrial process control, our Coriolis Mass Flow Meters deliver direct mass flow measurement without needing fluid temperature, pressure, or viscosity compensation. By measuring fluid inertia via the Coriolis effect, these sensors provide multi-variable output—simultaneously reading mass flow rate, fluid density, and process temperature in real time.
Whether you are dosing aggressive chemicals, managing custody transfer of oil and gas, or maintaining hygienic processing standards in food and pharma, Coriolis flow meters provide low maintenance and high operational repeatability.

DIGITAL DISPLAY MASS FLOW CONTROLLER
Real-Time Flow Monitoring and Active Control in One Integrated Device
A Digital Display Mass Flow Controller (MFC) combines a high-accuracy mass flow sensor, a fast-acting proportional control valve, and an integrated digital readout into a single compact unit. Designed for precise gas delivery in laboratory research, semiconductor manufacturing, and industrial automation, it actively measures and regulates gas flow rates regardless of upstream pressure fluctuations.
Unlike standard mass flow meters that only read flow rates, a controller actively regulates flow to a specified setpoint via local buttons or digital communication protocols.
