Smart mass flow meters and controllers for gases
The thermal mass flow meters and controllers of the series red-y by Vögtlin Instruments determine and control very exactly the mass flows of air and gases. Its easy handling and compact design offer considerable benefits.
Passing a flow divider a defined part of the flowing gas is conducted to the mass flow sensor. The medium is heated there as previously defined and the temperature difference between input and output of the mass flow sensor is measured. By knowing the bypass divider relation the total mass flow can be determined.
Main Features

GCx – compact mass flow meter
The flow meter and controller of the compact series GC replace variable area flow meters in their previous fields as local flow indicator and target also mobile application possibilities.
In addition to the benefits of network independency – thanks to battery-powered operation – and the flow adjustment via manual control valve the devices offer a clear added value to your system by an accurate and clearly readable display, pressure independency and intelligent watchdog/limit value functions. GCx mass meters are suitable for operating pressures up to 10 bar.

GSP – Electronic pressure control with integrated flow measurement
The new electronic red-y smart pressure controllers combine the reliable technology our of thermal mass flow controllers of the Smart series GSC with an electronic pressure control.
The devices automatically control a predefined process pressure and at the same time measure and/or limit the flow rate. On-the-fly switching between pressure control and flow control offers maximum flexibility.
