Practical Pipeline Metering for Irrigation Networks Irrigation Paddle Wheel Flow Meter is designed for pressurized irrigation mains, pump stations, fertilizer injection systems and farm distribution pipes. Large networks need affordable measurement points, but sand, weeds and unstable pump discharge can damage or distort a small rotor sensor. A paddle wheel meter provides a simple flow signal for pump checks, application-rate control and water-use tracking without the cost of a full-bore meter at every site. Insertion Design for Broad Pipe Coverage A compact rotor turns as liquid passes the insertion point, producing a frequency proportional to local velocity. The transmitter applies the pipe factor to calculate flow rate and total, providing an economical solution for clean water and compatible process liquids. Gallop describes the paddle wheel series as a stable, cost-effective instrument with typical accuracy within 1 percent. Its compact insertion format is especially useful when full-bore meters become costly at larger diameters or when multiple monitoring points are needed. The pipe must run full and the fluid should be clean enough for the rotor to turn freely throughout the season. This page can naturally support buyer terms such as paddle wheel flow meter, insertion flow sensor, economical liquid flow measurement, pulse output flowmeter and water flow monitoring. Protect the Rotor From Sand and Debris Confirm inside diameter, fitting geometry, velocity range, filtration and straight run; position the sensor to avoid trapped air and sediment accumulation. Use pulse totalization or a transmitter signal for the irrigation controller, and retain the pipe factor and insertion-depth setting for repeatable service. Paddle wheels are not the first choice for abrasive slurry, fibrous wastewater, heavy coating, very low velocity or locations that cannot be isolated for service. Straight run and a completely full pipe remain important for dependable velocity profiling. Gallop has focused on flow and level instrumentation since 2005 and presents in-house R&D, ISO 9001:2015 and CE evidence.
