1. Domestic Static AMR Water Meter

iPERL® (International) are next-generation, high-performance, solid-state smart water meters with integrated bi-directional communications capability. iPERL meters use a unique technology that provides unrivalled, sustained accuracy over their expected 15-year operational life.

With a low-flow measurement of 1 litre per hour, iPERL helps utilities to reduce non-revenue water. They can be programmed to provide highly granular data at 15-minute intervals, which improves accuracy in identifying customer-side leaks. The wealth of data also helps water utilities to manage distribution networks more efficiently, to conserve water, to provide accurate billing to customers and to inform them about leaks, fraud or unusual usage patterns.


2. C&I Static AMR Water Meter

Cordonel is a high-performance bulk meter that enables you to manage your distribution network more efficiently and provides accurate and reliable data in any installation or environmental condition.

Using advanced ultrasonic technology and a Sensus communication network, this meter gathers precise low and high-flow data in real time. This solid state meter has no moving parts and offers a patent-pending flow tube with no obstructions, providing a maintenance-free meter over its operational lifetime.


3. C&I Mechanical AMR Water Meter

MeiStreamRF is an industrial meter with electronic register for:

  • Measurement for billing of cold potable water up to 50 °C
  • Measurement of medium and high flow rates
  • Measurement of low flow (e.g., in light load period)
  • Leakage control
  • Integration into Smart Water Networks
  • Sizes from DN 40 up to DN 300

The MeiStreamRF has Sensus RF integrated technology, providing the advantages of both unidirectional and bidirectional communication. Sensus RF is the optimized radio system for battery-powered endpoints. Scalable for mobile and remote reading without exchange of components, it is available in 868 MHz and 433 MHz.


4. MeiStream and MeiStream Plus

MeiStream® is an industrial meter for:

  • Measurement for billing of cold potable water up to 50 °C
  • Measurement of high flow rates (e.g., in pumped pipes)
  • Measurement of low flow (e.g., in light load periods)
  • Leakage control
  • Sizes from DN 40 up to DN 300

MeiStream® Plus is an industrial meter for:

  • Measurement for billing of cold potable water up to 50 °C
  • Measurement of medium high flow rates (e.g., in pumped pipes)
  • Measurement of low flow (e.g., in light load periods)
  • Leakage control
  • Available in sizes from DN 40 up to DN 150

5. WP Dynamic

WP-F Dynamic is a protection sieve that is installed to protect a water meter from damage. The heavy-duty sieve element retains any large particles. Cleaning of pipes after maintenance or rupture in the pipe.

The WP-Dynamic BMF is a Woltman turbine water meter that is copper alloy-free for cold water up to 50 °C and hot water up to 130 °C.

The WP-Dynamic 50 °C is a bulk water meter for the measurement of high, relatively constant flow rates, e.g. behind pumps. It is available in sizes DN 40 to DN 400.


6. WPD FS

The flow sensor WPD FS 130°C is used for measuring hot process water in heating systems with high relatively constant flow rates. Available in sizes DN 40 up to DN 300.

  • Approved in DN 50 to DN 150 for customer billing acc. to 2014/32/EU MI004
  • Installation in vertical, horizontal or inclined pipes
  • Available in short and long body lengths
  • Can be equipped with up to three pulsers (1xOD, 2xRD)
  • For measurement of hot process water up to 130 °C

7. MeiStream FS

The MeiStream® FS Flow Sensor 90 °C combines the high reliability and measurement accuracy of the Woltman WP meter with the advantages of the Woltman WS meter in the lower measuring range. This combination creates an excellent flow sensor with an MID approval according to MI004 or EN 1434 in the accuracy class 2.

Volume pulses are generated by the interface HRI-Mei FS. This interface transfers volume pulses with programmable pulse values to the heating or cooling calculator. Possible reverse flows are compensated.


8. Compound Water Meter

The MeiTwin is a compound meter for cold water up to 50 °C that measures high flow rates and very small flow rates for extremely widespread flow profiles.

The MeiTwinRF with MID approval is a compound meter with integrated radio for measurement of high flow rates as well as very small flow rates for extremely wide spread flow profiles.


9. Turbine Water Meter

The WP QF water meter measures cold water up to 40° C (overloadable up to 50° C) in water supply pipelines with pressure up to 25/40 bar. It also operates as a flow sensor for heat meters. It measures hot water up to 130° C (overloadable up to 150° C) in heating systems with pressure up to 25/40 bar.

The DN 500 model measures high, relatively constant flow rates in long-distance pipes.
