The 280W-CI commercial and industrial ultrasonic water meter from Spire Metering Technology has no moving parts and retains its accuracy over its lifetime. It has quad path technology, which means there are eight different sensors to improve accuracy, increase tolerance to installation errors by local installers, 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, is not affected by water impurities and withstands harsh environments. It can detect very low flows, and comes AMR/AMI ready so leakages found by the meter can be sent quickly to the central office without human intervention. 888/738-0188; www.spiremt.com.
