The RBBW-I is a battery-powered insertion ultrasonic water meter for agricultural irrigation, garden management and water supervision. Insertion mounting keeps pressure loss at zero, and the ultrasonic principle has no rotating parts, so accuracy holds up in water carrying gravel and weeds.
A built-in volume controller and time accumulator enable automatic, scheduled and quantitative water supply, while time-sharing flow accumulation supports gradient and rate-based billing.
The RBBW-I offers ISO 4064 Class 2 accuracy, verified through our ISO 9001-managed factory calibration process.
The RBBW-I is available for pipe sizes from DN65 ~ DN150, supporting a wide range of industrial flows.
The RBBW-I supports OCT×2/TTL pulse, 4-20mA, RS485/USART/IR (M-Bus optional) output for integration with your control system.
Selection depends on fluid conductivity, pipe size, temperature, and accuracy needs. Electromagnetic meters suit conductive liquids, ultrasonic meters suit large pipes and clean liquids, and vortex meters handle steam, gas, and liquids. Contact R&B Instrument Inc. engineers for a recommendation.
Inline flanged transit-time ultrasonic flow meter for industrial water and process liquids, factory calibrated with no moving parts and zero pressure drop.
Fixed Doppler ultrasonic flow meter for open-channel and partially-filled pipe flow with dual-depth area-velocity technology.
Inline ultrasonic micro-flow sensor measuring 1–100 mL/min with millisecond response, no moving parts and a biocompatible PEEK fluid path.
