The OPTICHECK flowmeter verification tool from KROHNE provides in-situ verification for mass and other flowmeters. When connected inline, the tool gathers data to ensure a flowmeter is performing within 1 percent of factory calibration, with a confidence level of 95 percent. The baseline for comparison can be historic repair data from the factory or on-site test results. The lightweight, portable tool can verify OPTIMASS Coriolis mass meters, OPTISONIC ultrasonic flowmeters and OPTIFLUX, TIDALFLUX and WATERFLUX electromagnetic meters. It provides a hard copy report as well as digital storage of verification data. Cables and accessories are included, as well as an option to download factory calibrations. 800/356-9464; www.us.krohne.com
