It is a modern alternative to traditional float and probe gauges, using \u003cstrong\u003e60 GHz pulsed coherent radar\u003c\/strong\u003e to measure the distance to the liquid surface without the sensor needing to touch the stored liquid.\u003c\/p\u003e\n\u003cp\u003eDesigned for oil, fuel, water and industrial liquid storage applications, the TEK 920 combines radar measurement with \u003cstrong\u003eBluetooth 5.0 Low Energy (BLE)\u003c\/strong\u003e, a local digital display and a rugged outdoor enclosure.
