Flow Monitoring for Wet and Flood-Prone Locations IP68 Paddle Wheel Flow Meter is designed for valve chambers, outdoor water systems and locations exposed to washdown, condensation or temporary flooding. Moisture can enter connectors, splices or remote electronics even when the sensor body itself carries a high ingress rating. An IP68-rated paddle wheel configuration can provide economical flow feedback where a standard indoor enclosure would be vulnerable. Separate Sensor Protection From System Protection 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 complete installation must be reviewed, including sensor, cable, connector, junction box and transmitter, because the lowest-rated component controls reliability. 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. Confirm the Real Immersion and Cable Requirement Specify immersion depth and duration, cable length, chemical exposure, pipe size, velocity and service access; use approved sealed connections and strain relief. Locate displays and power interfaces above flood level where possible, and request model-specific IP test evidence rather than applying a sensor rating to the entire system. 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 states a one-year warranty, long-life maintenance and installation guidance. Include commissioning support, spare-part recommendations and response expectations in the commercial review so service terms are as clear as the instrument specification.
