Thread liquid turbine flow meter features compact threaded connections for DN4-DN80 pipelines, with stainless steel body delivering high-precision measurement of clean low-viscosity liquids. It supports pulse and 4-20mA,hart and RS485 signals output, ideal for fuel, water and solvent small-bore pipeline metering.
Compact small-size threaded structure, suitable for DN4~DN50 narrow pipeline installation.
High accuracy and good repeatability for clean, low-viscosity liquid media.
Stainless steel wetted parts with good mild corrosion resistance.
Convenient thread mounting without complicated flange welding.
Multiple signal outputs: pulse, 4-20mA and RS485 optional.
Small pressure loss, lightweight and easy disassembly for maintenance.
Optional explosion-proof design for small chemical fuel pipelines.
