Pulse meters for cold and hot water

W A T E R    M E T E R S

 

 With impulse contact for hot and cold water, dry-rotor version

These meters are fitted with an impulse trasmitting contact and so can be connected to a data collection system for consumption data to be recorded. Counting impulses are released by a Reed contact.

In dry-rotor version meters the totalizer is encapsulated in a watertight compartment and so is protected from dirt and contamination.

 

Cold water: max. 40°C

Hot water: max. 90°C

 

The use of such meters is desirable with water of poor quality where is a risk of the mechanism becoming clogged with sludge or sand.

Multi-jet meter water flows throught a number of inlet channels around the impeller chamber. This ensures an even loading of the impeller bearing, and thus prevents their wear, even with severe fluctuations in the rate of flow.

Use is only made of high-quality, wear-resistant materials.

The measuring units meet the requirements of the German physical testing laboratory (PTB) and EU standards.
