NIVUS manufacture non-contact ultrasonic level measurement products. The product range comprises ultrasonic sensors and meters. Sensors such as the NivuCompact echo sounder can be used at any place where reliable non-contact level measurement is required. Due to the non-contact measurement system the P-Series sensors are very low in maintenance and among other areas are used for level and flow measurement in the water and wastewater field. Since i-Series sensors and meters share a fully encapsulated enclosure the system can be installed very easily featuring low space requirements. Pre-programmed measurement range steps virtually eliminate the need for extensive programming measures. The sensors can be connected directly to any PLC, NIVUS GPRS-data loggers and all systems processing readings featuring active mA-inputs.
