HWM’s SonicSens is a versatile ultrasonic level sensor with a 5 year battery life, designed for easy installation and ready to output results either locally or via a range of telemetry options. The SonicSens combines precise ultrasonic measurement with a connected MultiLog data logger to store, interpret and transmit results, making it suitable for a wide variety of level-sensing and flow monitoring situations. The option of cellular wireless telemetry and the long battery life mean that the device is ideal for remote installations where constant access is difficult and traditional communications unsuitable.

Open channel flow or level monitoring is made easy by the non-contact ultrasonic sensor, taking instant and accurate readings of targeted surface levels – including Combined Sewer Overflows, which must be monitored, as required by European legislation. Fluid levels in tanks or storage containers can also be remotely checked, with easy mounting options allowing for temporary survey type operations. Data from the SonicSens 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 itself to maximise signal. Also incorporated are echo-loss alarms, intelligent self-diagnosis, variable blanking distance, and automatic interference rejection based on rate of change to discount false readings.

Versatile logger features multiple telemetry options

Cincinnati, OH (August 14, 2009) – Providing unique measurement and datalogging technology, Halma Water Management (HWM) introduces the new Octopus logger.

The Octopus logger is ideal for environmental datalogging in a variety of situations, such as rivers, tanks, reservoirs and pipes.  The unit is designed for multiple applications including open channel level and flow monitoring, flow rate and rainfall measurement, pump usage and network pressure monitoring.  The logger features a 5 year battery life, multiple inputs and outputs, and a fully submersible waterproof housing. 

In addition to its datalogging capabilities, the Octopus logger has multiple integrated telemetry options, including GSM and PSTN Landline, to automatically transmit data to the user when it is collected.  A switch output allows it to drive additional equipment such as samplers.

The Octopus uses HWM’s Winfluid software, which configures the device, records its findings and interprets results through automatic conversion algorithms to produce immediately usable data.

Wireless telemetry specialist Radio-Tech will be showing its range of energy management and sub-metering equipment at the Energy Solutions Expo 2009.

The company’s wireless data capture technology allows for 24/7 monitoring of remote assets and consumption of water, electricity and gas; regular reports on consumption allow usage to be cut, reducing both bills and environmental impact.

Central to the range is the new GPRS concentrator, the RT: Wi5, that receives, stores and transfers radio packets from the company’s UHF / VHF transmitters and boosters. The data transmitters, having collected relevant data, feed wirelessly into the RT: Wi5 from a range of up to 2.6km without repeaters, meaning a single receiver is able to cover large sites. It operates on Radio-Tech’s exclusive and licensed frequency of 153 MHz and can retrieve data either locally (via USB) or remotely (via Ethernet, WiFi or GPRS / GSM).

Radio-Tech’s stand will be manned by UK sales managers Craig Anderson and Chris Bridge, and marketing manager Helen Clarke.
