Wireless fuel consumption meters DFM-S7

DFM S7 for direct measurement and recording of fuel consumption with a kinematic viscosity of 1.5 to 6 mm2 / s. DFM S7 wireless fuel flow meters are used in vehicle telematics (GPS / GLONASS vehicle tracking), online monitoring systems of stationary engines, boilers / heaters and as a stand-alone solution for monitoring fuel consumption. The flow meters are based on S7 technology, which provides wireless data transfer via Bluetooth 4.X (Bluetooth Low Energy) to multiple devices using BLE radio. In other words, the flowmeters operate in "advertising" mode - data is transmitted simultaneously to telematics units and GPS trackers, Bluetooth displays, smartphones and tablets.

Note: To ensure proper operation, we recommend returning the flowmeter to us in time to replace the battery.
