Heater Enable

The FS1023 allows power savings through the operation of the Heater Enable (HE) pin. The flow sensor element includes a micro-heater. The

HE pin powers the micro-heater. When a measurement is taken, the HE pin must be powered on and connected to +5VDC. To conserve power,

the HE pin can be pulsed on when taking measurements or grounded (turned off) when no measurements are required. Alternatively, the HE

pin can be constantly powered on.

Electrical Connector

A 6-position receptacle (not provided) is required to mate to the board crimp style connector. A part number example is PHR-6 (JST).

Module Material

The wetted contact surface of the FS1023 consists of the following:



Housing – Polyphenylene Ether (PPE) + Polystyrene (PS) blend resin



Flow Sensor – Silicon-carbide thin film



Epoxy



Gasket – Silicone



Substrate – Gold plating

Tubing Guidance

The FS1023 module has barb tube endings. Tubing with a nominal 3/8inch (9.5mm) internal diameter is recommended for use. A hose clamp

or zip tie can be used to secure the tubing.
