The 280W-CI commercial and industrial water meter from Spire Metering is an ultrasonic water meter, which means there are no moving parts to break and it retains its accuracy over the lifetime of the meter. It has quad path technology with eight different sensors to improve accuracy, increase tolerance to installation errors and reduce the straight pipe run requirements of typical ultrasonic meters. It can be used for district metering areas for leak detection. It has a tamper-proof design and is not affected by water impurities. It can detect very low flows and comes AMR/AMI ready so leakages can be sent quickly to the central office without human intervention. 888/738-0188; www.spiremt.com.
