Woltman flanged water meter LXLC is a water meter with the features of double flange connection, removable structure, larger capacity, lower pressure loss, and long service life; Its removable structure makes the water meter not have to be removed from the pipe, the mechanism can be pulled out for repair or replacement; The magnetic transmission structure makes reading clearer, it is available for both cold water and hot water. And also available with the pulse output.
The Woltman Flanged Water Meter (also known as a Helical or Turbine Meter) is a velocity-type water meter designed for measuring large volumes of water in industrial, municipal, and irrigation applications. Unlike traditional rotary vane meters, the Woltman design utilizes a helical rotor placed axially in the flow stream. This construction minimizes pressure loss and ensures high accuracy even at continuous high flow rates.
MIDAS Woltman meters are available in sizes ranging from DN50 to DN500, featuring a robust cast iron body with epoxy coating and a removable measuring element for easy maintenance without dismantling the meter from the pipeline.Get a QuoteMade from corrosion resistant materials.
IP68 protection for the head.
The head can rotate 360 ° for easy reading.
Interchangeable measuring unit.
