Meinecke Mechanical Turbine Water Meters

For over 100 years, the H. Meinecke Company has been manufacturing mechanical turbine meters for water applications. Meinecke meters are now widely used in power, municipal, agricultural and commercial applications where monitoring and totalizing of hot and cold water usage is critical.

Available in ANSI/DIN 150 LB flanges in sizes from 1-1/2 inch to 12 inch, Meinecke meters can be outfitted with a mechanical totalizer or connected to a frequency to current converter to provide a 4-20 mA signal output. Meinecke also manufactures the BMF series of meters in sizes from 2 inch to 8 inch for light caustic service. 

MEINECKE WP/Dynamic Series Flow Meters are ANSI Flanged Mechanical Totalizing Turbine Woltman Water Meter style. They are available in sizes ranging from 1-1/2" to 12", in both Cold (<122°F) and Hot (<266°F) water versions.

Meinecke introduced the WP/Dynamic Series Turbine Meters in 2001. Like it's predecessor, the WP/Dynamic Series Turbine meters offers a simple, time tested method flow measurement, but at the same time, one that's been updated with state of the art technology.

  • Measuring ranges have been extended, with required minimum flows at unheard of lows when compared to typical turbine type water meters.
  • Reaction times have been improved and durability has been maximized.
  • Reconfigured pulser ports for both reed and opto style pulsers allow for easier installation in both new and retrofit applications. Pulsers simply plug into the register head rather than under the register as was common on the WP-QF series. No tools or special skills are required. There are a total of three ports, two REED and one OPTO.
  • Most noticeably, the new body design allows for minimum straight pipe requirements of just 3 pipe diameters upstream and ZERO (0) downstream. Similar meters from other manufacturers require the industry standard of a minimum of 10-15 pipe diameters upstream and half that much downstream.
  • Standard Process Connections are ANSI 150lb R.F. Flanges.
  • Register Options include US Gallons and Cubic Meters.

We typically stock all sizes of the Cold Water Meters from 1-1/2" to 12". Need a water meter on site in 24 hours? Call us! We even stock 8", 10" and 12" cold water meters.

Mechanical, Non-Resettable Totalizing Register

Available in US Gallons and Cubic Meters, the improved design of the hermetically sealed register has resulted in a major improvement in its ability to keep out moisture and dirt. It can be rotated in any direction without affecting the meter reading or calibration seal and the register face has been redesigned to make it easier to read in poor lighting conditions. 

Maintenance and Repairs

Meinecke's flanged propeller meters consist of two parts, the flanged body and the Internal Measuring Unit (IMU). The IMU is a modular part consisting of the propeller assembly, register and the transmission/counting mechanism. Removal of the measuring element for cleaning, maintenance and/or replacement is a simple procedure and can be accomplished without removing the meter from the line. Spares IMU's for Cold Water meters in sizes ranging from 1-1/2" to 6" are typically available from stock. 8 inch to 12 inch Cold Water IMU's all Hot Water sizes are special order products with 4-5 week lead-time.

Electronic Accessories - Pulsers, Current to Frequency Converters

REED Type 01 - 02 - Low Frequency Pulsed Output

  • The RD-01 is a 2-wire, low frequency volt-free contact closure pulse for use with the WPD Cold Water Meters.
  • The RD-02 is similar to the RD-01, but designed to withstand the higher temps typically found in Hot Water Applications.
  • Reed Pulsers are typically used as the standard input to flow counters, totalizers, etc. A reed switch is encapsulated in the counter and is switched by permanent magnets fitted within the counter mechanism. One note of caution… continuous contact can occur when the water flow stops. Connected devices must be suitably protected.

Application Note: Pulsers designed for hot water service can also be used for cold service if needed.

OPTO Type 01 – 02
High frequency pulsed output

  • The OPTO-01 is a 2-wire current switching device for use with WPD Cold Water meters; The OPTO-02 is for use with Hot Water meters. This type of pulser is normally used for conversion to analog signals, (4-20mA) or as inputs to high definition dosing/batching units. Light pulses are transmitted by an IR light diode onto a reflector wheel. The reflections are picked up by two detectors in the sensor head and processed electronically. The micro-electronics are located in a capsule within the cable

FM-1/DK – Frequency to Current Converter

The FM-1D/K is a remote mount "Frequency to Current Converter" which converts the pulsed output from a WP/Dynamic Series meter equipped with an Opto style pulser into an analog 4-20mA signal, as well as a remote mount display of flow rate and total.

Note: We stock the FM-1D/K (Part Number: 182023) configured for 115VAC/24VDC power and registration in US Gallons. Use P/N: 182021 (special order) for M3 measurement.
