Our thermal dispersion flow switches are specifically designed for the harshest of applications in liquid or gas. They are both ATEX Exd certified and SIL2 rated.
Thermal dispersion technology measures the temperature difference between an active (heated) RTD and a reference (un heated) RTD. This is greatest in a no-flow condition and decreases as flow increases, cooling the heated RTD. Changes in flow velocity directly affect the extent to which heat dissipates and, in turn, the magnitude of the temperature difference between the RTDs.
A basic, general purpose flow switch for pipe sizes of > 1 ½"
The FS10i is a low cost, thermal flow monitor for liquids & gases, SIL2 compliant, ATEX certified with no moving parts.
Bespoke designs for a wide range of applications, pipe sizes from 1 ½ to 1m diameter.
An "in line" design, for low flow applications in gas or liquid.
Specifically designed for liquid and gas analyser applications.
