Measuring technology for flow rate, mass flow rate and flow velocity

Probe ZS25 ... ZG4

Probe ZS25 ... ZG4

Probe ZS25 ... ZG4 - standard for fixed measuring - with connection housing

Cylindrical vane wheel sensor / insertion probe with probe diameter 25 mm and integrated transducer UFA (optional).

Probe material: stainless steel.

Working temperature range up to +550 °C.

Suitable for fixed measuring of actual flow velocity v [m/s] and flow rate V/t [m³/h, l/min] in clean gases and liquids, briefly also in particle-laden mediums.

Signal evaluation with integrated or separate transducer UFA, flowtherm NT, flowtherm Ex and system units.
