Sight flow meter | range 4.0-20.0 GPM | 110 VAC | 1/2" female NPT.
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
