Descripción
HRV-W:
It is a meter that uses an axial turbine as a speed sensor, the axis of the turbine coincides with the axis of passage of the water, with magnetic transmission and dry sphere. The special design of the turbine allows it to work with high sensitivity at low flow rates. The measuring insert is encapsulated and rotatable. The visor does not fog up internally,
ensuring easy reading. The loss of load due to measurement effects is minimal. our accountants
Woltman are characterized by their high measurement stability.
FEATURES:
- Approved U0-D0 (no need for straight sections upstream or downstream).
- Body in ductile cast iron with epoxy paint for food use, baked.
- Fully removable mechanism without the need to disassemble the meter from the pipe and manufactured
with technical plastics in combination with stainless steel for the metal parts. - Optimum hydraulic performance. The accountant has the following certificates:
-Type Examination Certificate for irrigation water by the CEM (Spanish Metrology Center)
