WWM-25Q Series Aluminum Electronic Presetable Waist Wheel Flow Meter (Pump-Controlled Liquid Measurement)

WWM-25Q Series Aluminum Electronic Presetable Waist Wheel Flow Meter (Pump-Controlled Liquid Measurement)

The WWM-25Q Series is a high-precision electronic preset waist wheel flow meter with a lightweight aluminum body, designed for seamless integration with electric transfer pumps. Its compact and portable design allows precise liquid dispensing and automatic pump control in diverse applications, making it ideal for fuels, AdBlue, chemical liquids, and other clean fluids.

Equipped with a digital LCD display, users can easily set unit price, target volume, or amount. Once the preset volume or amount is reached, the pump automatically stops, ensuring fully automated operation and minimizing human errors. The meter supports DC12V, DC24V, and AC220V, providing broad compatibility with various pump systems for flexible and reliable operation.

The slim waist wheel mechanism is the core feature of this series. By rotating the waist wheel, the meter achieves stable flow under both low and high flow conditions, maintaining high measurement accuracy (±0.5%) and excellent repeatability. Its durable mechanical structure ensures long-lasting performance, even in continuous operation.

Internationally, the WWM-25Q Series is known by different names, reflecting its global acceptance:
Electronic Preset Waist Wheel Meter (Europe & US)
Digital Rotary Paddle Flow Meter (Asia)
Medidor Electrónico de Rueda de Cintura con Preajuste (Latin America)
Compteur à Roue de Taille Électronique Préréglable (France)
