STFX5000 CLAMP ON ULTRASONIC

TRANSIT TIME ULTRASONIC

The transit time ultrasonic flow meter measures volumetric flow and heating/cooling energy rates in clean liquids as well as those with small amounts of suspended solids or aeration, such as surface water or raw sewage. STFX5000 flow and energy meters clamp onto the outside of pipes and do not contact the internal liquid.

Applications

The STFX5000 meter is available in a variety of configurations that permit the user to select a meter with features suitable to meet particular application requirements.

The STFX5000 meter is available in two versions:

  • A flow meter for water delivery, sewage, cooling water, water-glycol mixtures, alcohols and chemicals
  • A heating/cooling energy flow meter used in conjunction with dual clamp-on RTDs for temperature measurement—ideal for hydronic process and HVAC applications
