Water meters types GZRF and GMZF are Class B Multijet and Woltman water meters for use on cold water up to 16 bar pressure and conform to standards ISO4064 and BS5728. They all have a magnetically driven wet or dry register, which are freely adjustable to give easy reading.
Both types of water meters can be supplied with pulsed outputs if required by the addition of a contact read switch and it is possible to select or change to one of twelve pulse output values on many meter sizes. | |
