Series SFI-800 Sight Flow Indicator/Transmitter
Brand: Dwyer Instruments, LLC
The Series SFI-800 Sight Flow Indicators & Transmitters is 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.
There are three output sensors available, the A-711 offering two pulsed voltage signals proportional to flow rate, the A-712 which outputs a linear 1 to 10 Vdc signal proportional to flow rate, and the A-713 which offers two programmable open collector switch outputs.
The Model A-711 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.
The Model A-712 is a sensor that outputs a linear 1 to 10 Vdc signal proportional to flow rate.
The Model A-713 is a sensor with two programmable open collector switch outputs with one output closed above the set point and the other output closed below the set point ideal for low flow or high flow indication.
Features- Constructed of clear plastic enabling 360° viewing of the rotor for easy flow indication
- SFI-800 models are constructed of Polysulfone with excellent chemical compatibility, high pressure and temperature ratings, and all wetted materials are FDA/NSF ratable for potable water applications
- SFI-801 models are constructed of UV stabilized Polycarbonate making them ideal for outdoor applications and easy view bright red impeller
- All three output packages cam be installed or replaced in the field without any tools and without removing the body from the process line
- Units are weather-tight for outdoor or wash-down area use
- A-713 features a user-friendly set point button which is set at the desired flow rate with red LED indication of switch status
