Ultrasonic bulk water meter IUW

The IUW ultrasonic bulk water meter is used to record high and fluctuating flows in drinking water distribution and in industry, with a very low pressure loss at the same time.

Two pairs of ultrasonic sensors ensure optimum measurement accuracy. The IUW is factory-fitted with a 9-digit LCD display and an NFC interface. This enables a subsequent connection of a wM-Bus (OMS) or LoRaWAN®-NDC module. Via the plug and play function of the NDC module, the radio technology set on the meter is automatically adopted by the NDC module.
All variants are approved for horizontal and vertical installation and are therefore also suitable for installation in standpipes and downspouts.
All materials, which are used in the drinking water section, comply with the required standards, guidelines and
the current German drinking water approval (other country-specific drinking water approvals on request).
