01

Product overview

Flowtrecs Wave combines fuel measurement, engine data and safety functions on a bright 4.3-inch touchscreen. Its waterproof IP68 housing is designed for exposed helm positions. The system supports configurations with 1, 2 or 4 FS-40 sensors.

02

Key features

  • Supports 1, 2 or 4-sensor variants: 1 for one petrol engine, 2 for two petrol engines or one diesel engine, and 4 for two diesel engines.

  • Shows consumption, fuel economy in km/l, fuel remaining, range, speed, RPM, voltage and engine hours.

  • Built-in GPS supports speed measurement and trip statistics.

  • Anchor alarm and MOB functions assist at rest and in an emergency.

  • The capacitive screen provides quick access to clear instrument views.

  • The sensor kit is factory-calibrated and configured for the ordered version. No manual calibration or selection of sensor type, range or count is needed for first use.

Connecting the RPM signal

Reading RPM from the ignition signal of a carbureted petrol engine requires an additional Tacho Pulse Limiter. Two versions are available: IN — for inboard engines and OUT — for outboard engines.

For fuel-injected engines (EFI/DFI), a limiter is typically not needed when using a suitable electronic tachometer output.

The limiter is used only for RPM readings and is not required to measure fuel consumption.

Diesel: an additional Hall sensor may be required if the engine does not provide a suitable electronic RPM signal.
