Description
Veethree’s reed switch sender is compatible with a variety of fuel and fluid types, including; gasoline, diesel, hydraulic fluids, black water and grey water. The reed switch sender unit provides liquid level information via a series of reed switches positioned inside the sealed level tube, a float with built in magnets then triggers the reed relays generating a resistance with an ohm value that increases or decreases. The float is the only moving part of the sensor, thereby minimising potential mechanical failures and maximising flexibility of installation even in tanks with baffles.
