Scale Flow Monitoring Without a Full-Bore Meter Large Pipe Paddle Wheel Flow Meter is designed for large water, cooling and compatible process lines where moderate accuracy and low installed cost are priorities. A small insertion sensor can cover a wide pipe range, but its local velocity reading is only useful when the profile and programmed pipe area are correct. Paddle wheel technology reduces meter-body size, flange weight and purchase cost for multi-point monitoring. Use Pipe Factor and Insertion Depth Correctly 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 best applications are full, clean pipes with stable velocity and enough straight run to create a repeatable profile. 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. Preserve a Representative Velocity Profile Measure true inside diameter, confirm fitting dimensions and insertion depth, and locate the sensor away from pumps, valves and elbows or use a suitable conditioner. Program the pipe factor consistently in the transmitter and receiving system, then validate against a reference during commissioning. 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. The current product pages list project ordering from one unit and OEM or ODM availability.
