SFI-801-3/4-A711

SFI-801-3/4-A711 is a series SFI-801 polycarbonate sight flow indicator with A-711 sensor. It is a low cost, durable rotor style flow indicator with optional Hall Effect magnetic output package to combine visual confirmation of flow with optional remote flow monitoring. It is constructed of UV stabilized Polycarbonate making them ideal for outdoor applications and easy view bright red impeller. The A-711 offering two pulsed voltage signals proportional to flow rate. The Model A-711 is a unique and patent pending sensor that outputs two pulsed voltage signals with one providing a 5VDC pulse and the other a pulse of the input supply voltage used, ranging from 8-18VDC. Typical applications include cooling and lubrication circuits, HVAC systems, aggressive chemical metering and batching systems.
