2 Technical description
2.1 Description
The FMT 3 is a flow meter for flowing liquids based on the measuring principle of a turbine wheel
meter. It can be used as a fixed meter or as a manual flow meter.
The FMT 3 is not to be operated with flammable and potentially explosive liquids with a flash point
< 55 °C. Liquids with a flash point above 55°C may not be used with the unit if they are heated
beyond their flash point.
The FMT 3 turbine meter consists of a measurement tube with a turbine and an electronic housing
which contains the evaluation electronics, display, and keypad. The turbine is equipped with a
magnet which transfers the measurement pulses to a reed switch on the evaluation electronics
when a medium flows through it.
The FMT 3 has a non-resettable total volume memory and 8 resettable partial volume memory slots
which allow e.g. the fuel consumption of individual vehicles to be monitored.
Permissible fluids: diesel, fuel oil, water, AdBlue, radiator antifreeze (concentrated or diluted), other
fluids on request
