Our combined experience, technical expertise and unrivalled technology have made us world leaders within the water and energy management industries with a reputation for innovation, quality and service. With over thirty years experience we are committed to delivering an outstanding return on investment to utilities, contractors, consultants and facilities managers.

Many of our products are well known within the utilities sector and have been proven to deliver an excellent return on investment.  For example, our award winning Permalog noise logging system is a popular choice among leak detection operatives within the water industry, with many hundreds of thousands deployed on pipes listening for leaks around the world. Their use in El Paso, Texas was recently credited with saving the city 6 million gallons of water per day. Similarly, our Economise system has helped to establish us as the technology partner of choice for many energy management service providers. The system enables users to wirelessly and remotely monitor the consumption of water, gas and electricity meters.
