OPTICHECK Flowmeter Verification Tool


OPTICHECK provides in-situ verification for mass and other flowmeters, enabling operators to perform preventive maintenance and responsive service to ensure that installed flowmeters are performing to specification.


When it's connected in-line on-site, the tool gathers measuring data to ensure that the flowmeter is operating within 1% of the factory calibration, with a confidence level of 95%. The portable OPTICHECK is capable of verification of the range of OptiMass Coriolis mass meters, OptiSonic ultrasonic flowmeters, and OptiFlux, TidalFlux, and WaterFlux electromagnetic meters.


The device comes with all cables and accessories for easy connection and handling.
