Anwendung:

Volume measuring component for measuring heat for billing hot water consumption.


Merkmale:

  • Multi-jet impeller meters designed to the latest technical standards with completely dry running operation and magnetic coupling
  • The roller counter is dustproof and condensation-proof and can be rotated for easier reading
  • For installation in rising pipes and downpipes
  • The built-in pulse transmitter is cast in a waterproof enclosure and is easily replaceable
  • The pulse transmitter for volume measuring components is fitted with a 100 Ω, ¼ W protective resistor (cable length 3 m)
  • Facility for remote transmission of flow rates
  • The compact design in subassemblies simplifies maintenance and repair
  • Only the impeller operates in the wet chamber to prevent faults due to sediment
  • The meters are equipped with a sealed shield for protection against magnetic interference

Note

When using the contact water meters as volume measuring component, we recommend that the meters are selected so that the pressure loss of 0.1 bar is not exceeded at maximum load.

Order the pulse output without resistor for a low-resistance load, e.g. mechanical roller counters.
