OTT CBS Bubble Water Level Gauge

1. Product Introduction

A compact bubble water level gauge designed for continuous water level measurement. It features high range and high precision, with 4–20mA analog output and an SDI12 standard interface. The newly designed intelligent air pump reduces air volume while maintaining measurement accuracy, thereby saving system power consumption.

This product includes integrated purification and overload protection functions.

2.Application Areas

Wetlands, groundwater, slender and gentle slopes (wetlands), inlets of dams/bridges/reservoirs and sluices, bedrock foundations, tide wells prone to freezing or silting, short-term measurements, arid regions (reservoirs, dry valleys, etc.).
