There are two check kits available: SITRANS FUP1010 Water Check Metering Kit for water and wastewater applications, and SITRANS FUP1010 Liquid Check Metering Kit for liquid applications other than water. The kits have been developed especially for verifying the accuracy and performance of any brand or type of flowmeter. They can be used to verify the performance of meters based on any existing flow measurement principle: orifice, electromagnetic, ultrasonic, rotary piston, Coriolis, etc. In addition, they measure practically all conductive or non-conductive clean or moderately aerated liquids or liquids with suspended solids.
