Series SF2 Sight Flow Meters

SPDT or Pulse Output, Visual Flow Confirmation, Brass Body

The Series SF2 Sight Flow Transmitters combine visual confirmation of flow with a relay or pulse output. The SF2-1 offers a SPDT relay output and the SF2-2 offers a pulse output proportional to the rate of flow. The 4.5 to 24 VDC pulse output is compatible with most digital logic families.

Product Applications

Cooling and lubrication circuits
HVAC systems
Aggressive chemical metering
Batching systems

Brass, solid body construction, one piece composite rotor, and ceramic shaft deliversdurability with broader chemical, temperature, and pressure capabilities
Set points are fully adjustable over the specified flow range
The dynamic operation of the rotor guards against jamming and false actuation
