Contact-type water meters serve for volumetric measurement of flow amounts, and to control proportional metering systems. They are intended for horizontal installation in piping systems, and are suitable for registering the slightest amounts of water drawn. The contact water meters are notable for their excellent measurement service life even under extreme stresses tending to Qmax and Qmin, as well as through a low pressure loss.

Each contact-type water meter is designed for a minimum permissible operation pressure of PN 10 according to German DIN 2401. On special request, the contact water meter can be supplied in hot-water or VE water versions. The max. permissible contact load is 24 V (protective low voltage) and 0,2 A. Contact water meters are generally fitted with a roller-type counting mechanism.
