Ultrasonic Open Channel Flow Meter

High-Precision Non-Contact Measurement: Utilizing sound wave reflection, this meter provides accurate level detection with a 1mm resolution , ensuring long service life and minimal maintenance by avoiding physical contact with the liquid.

Universal Primary Device Compatibility: The system features preprogrammed tables for a variety of standard weirs and flumes , including Parshall flumes, Rectangular weirs, and V-notch weirs at multiple angles (30°/45°/60°/90°/120°)

Intelligent Environmental Adaptation: Includes an integrated temperature sensor to compensate for changes in the speed of sound , alongside excellent anti-interference capabilities and a low blind area for reliable measurement in harsh conditions.

Rugged Industrial Protection: Engineered for demanding outdoor sites with a rugged IP67 powder-coated aluminum enclosure for the transmitter and an IP68 protection rating for the submersible sensor.
Flexible Integration & Remote Monitoring: Equipped with standard 4-20mA analogue output and RS485 Modbus RTU digital communication , supporting up to 6 programmable alarm relays for comprehensive process control.
Eco-Friendly & Versatile Power Options: Features ultra-low power consumption (only 2 watts) and supports customizable solar power supply , making it ideal for remote, non-powered sites like agriculture irrigation channels.
