Flow & Level Switch

Our thermal dispersion flow switches, which includes level switch functionality, 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

  • Chemical injection – flow monitoring

    Offshore chemical injection systems are characterised by low flows, often at high pressure. The FLT93L is perfectly suited and capable of operating up to 800 BarG.

  • Pump protection – Prevent Dry Running – SIL2

    Nothing will damage a pump quicker than overheating due to dry running. The liquid acts as a coolant & without it the seals & bearings can easily be damaged which leads to expensive repairs & production down time. The FLT93 flow switch solves the problem !
