High-Precision and Robust: Ideal for Use in Rivers and Dams

The Quartz-type Water Level Gauge is a very accurate and durable pressure-based gauge designed to maintain stability over a long period. Its accuracy and durability are due to using a Quartz oscillator, commonly used as a frequency reference in clocks and communication devices. Due to its minimal aging deterioration, it’s suitable for water level monitoring in dams and rivers, where high precision and durability are required. Accurate water level data are crucial for issuing swift evacuation warnings, understanding dam water storage and proper gate operation, and making equitable and planned irrigation water distribution decisions. The Quartz-type Water Level Gauge is a trusted sensor that meets these needs.

World's Highest Accuracy at ±0.01％ FS

The accuracy of ±0.01％ FS is unparalleled. For instance, when measuring a water depth of 10 m with Quartz-type Water Level Gauge this accurate, the maximum measurement error is a mere ±1 mm. Accuracy options include ±0.01％ FS, ±0.02％ FS, and ±0.05％ FS.

Measurement ranges up to 0–70m are available. The body of the sensor is constructed from stainless steel, ensuring durability. This type has a long lifespan with minimal errors, making it perfect for large dams, major rivers, and small to medium-sized rivers. It's easy to install and maintain.

Highly Compatible - Signal Converter for Quartz-type Water Level Gauge

The Signal Coder receives signals from the Quartz-type Water Level Gauge to convert water levels, perform calculations, and output color displays. It offers high compatibility with existing and newly built monitoring systems with a vast selection of output signal options (DC4-20mA, RS485, Contact, RS232C, USB). It can also connect with tipping bucket rain gauges. It's compact in size and suited for all kinds of water monitoring systems, including river flood risk management systems, irrigation water management systems, and hydropower dam monitoring systems.
