The SFI-800 Sight Flow Indicators & Transmitters are a low cost, durable rotor style flow indicator with optional Hall Effect magnetic output packages to combine visual confirmation of flow with optional remote flow monitoring.
The A-711 output sensor (optional) is a unique and patent pending sensor that outputs two pulsed voltage signals with one providing a 5 VDC pulse and the other a pulse of the input supply voltage used, ranging from 8 to 18 VDC.
Electrical Specifications (for A-711 Option Only):
- Temperature Limits: -20 to 212F (-29 to 100C).
- Power Requirements:8 to 28 VDC.
- Output Signal: White lead: 5 VDC. Green lead: 8 to 28 VDC equal to supply voltage. Pulsed output with frequency rate proportional to flow rate.
- Accuracy: +/- 5% FS.
- Frequency Output Range:0 to 100 Hz.
- Electrical Connections: Black lead: Ground; White lead: 5 VDC out pulse; Green lead: 8 to 28 VDC out pulse; Red lead: 8 to 28 VDC supply.
- Viscosity Maximum: 200 SSU.
Product Applications : Cooling and lubrication circuits; HVAC systems; Aggressive chemical metering; Batching systems.
