ABB Instrumentation has introduced the AquaProbe 1 and 2 insertion electromagnetic flowmeters into the US market for clean water applications. AquaProbe 1, intended for permanent installations where power is available, connects with the ABB MagMaster transmitter. It offers 4-20ma analog output and HART Communication options. AquaProbe 2, powered by a battery pack, primarily serves temporary installations. Typical applications of AquaProbe 2 include checking, verifying, and certifying existing meters or performing water loss surveys and studies on water distribution, pump efficiency and trunk mains. It can also measure water flows in remote locations lacking power. Aquaprobe 2 comes with such options as AC power with battery backup, data logger, and pressure transducer. The EEPROM memory within the AquaProbe 2 simplifies set-up of replacement units, eliminating recalibration and configuration. The AquaProbe units come in lengths of 12, 20, 25 and 40in for pipe diameters from 8in to 320in. Accuracy is better than ±2% of flow rate and battery life lasts up to five years.
