Flow Sensors For Liquids

Thermal Flow Sensors use the calorimetric principle and are suited to a wide range of flow monitoring applications. They are easy to install and independent of temperature and pressure. These thermodynamic flow controllers don’t have any moving parts, which means they are robust and resistant to soiling. Controllers for fluids such as water, glycol mixtures or chemicals are available.

There are sensors that work with amplifiers as well as compact units with built in electronics. Various output options including switched, analogue, pulse and IO-Link are available. You’ll find versions with different supply voltages too.

Additional variations consist of high temperature sensors up to 160 °C, special sensors made from such materials as Hastelloy, Monel, titanium and tantalum with high resistance to chemicals, and programmable flow sensors with digital displays. The flow controllers are either screwed into the side of the pipe or added to the line itself in the form of inline sensors.

This PRODUCT SEARCH tool allows you to find the most appropriate sensor to suit the application, with selections for medium (liquid, gas, glycol), power supply, flow rate, supply voltage, output type, connection type, temperature range and ATEX category.
