Burkert Type 8020 PVC Insertion Paddle Wheel Flowmeter
Flow measurement hasn’t been easier. Using the BPF8200 Series flow sensor with matched sensor installation fitting, means you can assemble a complete flow monitoring or controlling system in minutes. Offers both accuracy with repeatability, this insertion sensor operates on a simple electromechanical principle, used in liquid flow applications worldwide.
Offered with a combination of fitting to suit short sensors that are matched with True union ended tees in sizes from DN15 – DN50 and long sensor versions that are matched with saddle type fittings for sizes ranging from DN50 – DN200. Remote capability lets you place your meter up to 50 m away without signal amplification.
Available in PVC – PP chemically resistant, non-contaminating housing materials. That is lightweight but strong, which makes it ideal for handling a wide range of liquids, including corrosive fluids in chemical processing. For processes involving acids and solvents, the PVDF (polyvinylidene fluoride) housing version is a tough fluorocarbon that is highly resistant to more severe fluids.
The sensor BPF8020 consists of a transducer and a paddle-wheel with ceramic bearings. The ceramic rotating axis is set on the end of a PVDF INSERTION sensor armature. The transducer is mounted inside the armature. In a 3-wire system, the signal can be displayed or processed directly. The output signal is provided via cable plug. When liquid flows through the pipe, the paddle-wheel is set in rotation. The non-wetted permanent magnets inserted in the paddle wheel generate a measuring signal which frequency is proportional to the flow velocity. A conversion coefficient (K-factor, available in the instruction manual of the fitting), specific to each pipe (size and material) enables the conversion of this frequency into flow rate.
Two electronic module versions with frequency output are available:
- with one pulse output (either NPN or PNP transistor output depending on wiring). An external power supply of 12…36 V DC is required. It is designed for connection to any system with open collector NPN or PNP frequency input.
- with one pulse “Low Power” output (NPN transistor output). An external power supply of 12…36 V DC is required. Can only be connected to separate versions of flow transmitters.
Key Features:
