FOSTER FW-BAR is woltman type water meter with magnetic transmission, super dry register for commericial and industrial applications, it meets to the requirements of ISO4064 standard.

MAIN FEATURES:

 All the materials in contact with water, consciously selected by the known resistance to corrosion;
 Cold water meter under current standard for lower than 30℃(T30), but FOSTER FW-BAR meter
can be used safely in water temperature up to 50℃(T50);
 Iron body with inside and outside epoxy coating for protecting the corrosion;
 Super dry register capsule which ensures the clear reading in any operating conditions;
 The Impeller is the only moving parts in contact with water permitting the most reliable;
 The magnetic transmission movement with the maximum reliability;
 Low pressure loss characteristics are due to minimum restriction and no change in flow direction as water flows through the meter
 For maintenance purposes the complete measuring mechanism may be quickly replaced with a pre-calibrated measuring mechanism
 Reed switch cable for pulse output as optional
 Different flange type as optional : Include DIN/ISO PN10/16, ANSI 125…
