The GPRS/UMTS data logger, manufactured by Nivus, is a system for automated transmission of measurement data with simultaneous sensor power supply. The system is designed to make operators independent from available power or data lines.
A built-in LTE modem helps the data logger provide a consistent connection from the sensor up to the provision of measurement data online including the option to automatically create individual protocols. The data logger is equipped with a multi-roam SIM module per default. Data transmission is provided free of charge for the first year of use. The devices are already registered in the Nivus Web Portal prior to delivery and hence can be called up there instantaneously – operators benefit from smooth commissioning.
The measurement system has options to automatically adjust the measurement cycles to custom-defined events such as in case of overshooting a certain water level. Alarms can be triggered automatically at certain events or in case of sensor errors as well. In addition to tables and charts on readings, the Nivus Web Portal further provides information on the battery status of the NivuLevel Mobile and hence can be used to schedule efficient maintenance visits.
Due to IP68 protection rating of level sensors and NivuLevel Mobile unit the system can be used even under extreme conditions. Sensors as well as the data logger can be used in Ex zone 1. Parameters can be set and the data logger can be operated wirelessly via smartphone, tablet or notebook on site. In case of bad weather, strong sunlight or difficult access to the measurement place, it is possible to set the device parameters from a protected area such as a service vehicle.
Typical applications for the NivuLevel Mobile are event logging in stormwater overflow tanks, level measurements in water bodies or in storage sewers.
