Halma Water Management’s Sonicsens ultrasonic level sensor, which has a five-year battery life, is ready to output results either locally or via a range of telemetry options.

Sonicsens combines precise ultrasonic measurement with a connected Multilog data logger to store, interpret and transmit results, making it suitable for a variety of level-sensing and flow-monitoring situations.

The option of cellular wireless telemetry and the long battery life mean that the device is suitable for remote installations where constant access is difficult and traditional communications are unsuitable.

Open-channel flow or level monitoring for any liquid are facilitated by the non-contact ultrasonic sensor, taking instant and accurate readings of targeted surface levels.

Fluid levels in tanks, reservoirs or storage containers can also be remotely checked, with easy mounting options allowing for temporary survey-type operations.

Data from the Sonicsens sensor can also be used as a control for other processes, allowing varying levels or alerts to have different effects.

The system is available in four different configurations to suit varying installation requirements and networking preferences.

It can be non-ATEX cable linked, ATEX cable linked with a Barrier box, ATEX radio linked to the logger outside the ATEX zone or the sensor, logger and cable all ATEX rated with total protection for completely below-ground installations.

Sonicsens can communicate via GSM, GPRS, PSTN radio or satellite and the communication module can be sited separately from the sensor to maximise signal.

Also incorporated are echo-loss alarms, self diagnosis, variable blanking distance and automatic interference rejection based on rate of change to discount false readings.
