    Products & Features

    Bopp & Reuther Messtechnik GmbH is a German-based manufacturer founded in 1872. The company is globally recognized for its expertise in high-precision flow, density, and concentration measurements. The company is best known as the inventor of the oval wheel meter principle (patented in 1932). Their current portfolio includes: 

    • Flow Meters: Oval wheel meters (OaP, OP, OI, OC, OK, Flowal, OD), Coriolis mass flow meters, turbine meters, vortex meters, and electromagnetic flowmeters.
    • Density & Concentration: for liquids and gases.
    • System Solutions: Dosing and filling solutions, flow computers metering skids
    Benefits
    • No Inlet/Outlet Needed: Oval wheel meters can be installed directly, saving space and piping costs.
    • Independence from Viscosity: Ideal for high-viscosity media where other technologies fail.
    • Low Maintenance & Durability: Long service life due to rugged construction.
    • Short Dosing Times: Electromagnetic flowmeters and Coriolis meters offer quick batching times, some under 0.2s, suitable for food/pharmaceutical industries.
    • Comprehensive Solutions: Tailor-made metering skids, including strainers, gas separators, and flow computers.

    Flap Flowmeter KLA

    In stock

    SKU: KLA Flap
    The KLA Flowmeter uses a flap which is deflected by the flow of the medium. The deflection angle is a direct indication of the flow through the pipe. The flap is gravity-loaded, thus the device can be used for the flow directions left to right, right to left and bottom to top. In the variant KLA-GS the medium be measured is directly visible through a glass in the flow indication unit. download pdf datasheet
