Level TROLL 400, 500 and 700 water level gauges

• 

Introduction: With the industry-leading water level, water pressure and temperature recorder, built-in recording function and built-in battery, the titanium body is very corrosive and the service life is greatly enhanced. It is integrated with the telemetry system and HydroVu data service to feedback you in real time All water monitoring sites. The water level gauge has the characteristics of long service life, accurate results, intuitive software and real-time function.

feature:
Less than 1 inch in diameter
Ventilated (measured) or non-ventilated (absolute) pressure measurement
Automatic atmospheric compensation (only for ventilation type)
Fully sealed, all titanium structure and sensor
NIST calibration report
Flexible communication protocol (4-20 mA, SDI-12, RS-485) to control gates, pumps, alarms and other equipment
Access data 24/7 and receive event notifications through telemetry systems, radio or other third-party data collection platforms
Rugged twist-lock cable (sold separately)
The recorder has low power consumption and the working life is usually up to 10 years
High-precision applications, usable ventilation (gauge pressure) system
Data can be easily exported to Excel, web-based management services or data analysis software
application:
Analysis of aquifer characteristics: micro-water test and pumping test
Coastal: Tide level/port water level and field/estuary research
Hydrological events: maximum water level monitoring, storm surge monitoring and flood control system
Long-term real-time monitoring of groundwater and surface water
Mining and governance
