1.Wastewater level monitoring in sewage networks Product introduction

Wastewater level monitoring in sewage networks is a dedicated device for monitoring the liquid level in sewage networks,It has its own battery, power supply and network communication.The GSW1 series integrated level meter adopts a radar and pressure integrated design, and can use radar, pressure or one of the water level sensors at the same time.

Radar measurement adopts the current advanced range measurement mode - FMCW frequency modulation continuous wave mode, which can replace laser range measurement radar, industrial ultrasonic range measurement radar and other products.

It also supports optional input pressure sensors, which can measure the water level of the pipeline network through the pressure and radar dual sensor measurement modes, and ensure the accuracy of the water level gauge measurement through algorithm analysis.

The product is small in size and compact in structure, and is suitable for a variety of distance measurement application scenarios such as pipeline network and outdoors.
