Operation

The FLD 698 Fluid Control operates by detecting the electrical resistance of fluids. With the presence of polar fluid at the probe sensing point, the output of the module is OFF. Upon removal of the polar fluid from the probe sensing point, the output of the module turns ON after the delay period of approximately 3 to 5 seconds.

Typical Conductive Fluids

	City Water
	Sea Water
	Water and Glycol
	Water and Oil
	Beverages such as Coffee & Soda
	Weak Acid
