Variable-area and piston-style flowmeters are offered with a Hart Protocol option. The meters can be used to monitor continuous process cooling flows such as cooling water, seal water, cutting oil, cooling jackets and heat exchangers. Another option is a mechanical switch to back up the transmitted signal. The variable-area vane and piston-style flowmeters are offered in 12 sizes and go up to 2000 psi pressure for flow ranging up to 500 gal/min. With CSA and CE certifications, the meters offer ease of installation and operation. They mount in line and in any orientation, with no straight pipe runs required.
