Ultrasonic Technology

Sanchuan’s ultrasonic meters use the Time-of-Flight method to measure water flow, sending ultrasonic pulses and calculating flow velocity via signal travel time differences.

Dual-channel designs minimize flow profile errors, while advanced piezoelectric transducers and high-resolution ADCs deliver accurate readings even at low flow.

The system integrates DSP for real-time signal filtering and compensation, ensuring precision and stability.

Ultrasonic meters achieve high accuracy (up to R400), stable measurement at low flow, and have no moving parts—eliminating mechanical wear and extending lifespan.

The modular sensor design allows easy upgrades and integration with communication modules like NB-IoT.

Robust construction, IP68 protection, and efficient power management support reliable performance in harsh or remote environments.

These meters feature real-time temperature and pressure compensation, remote calibration, fault self-checks, and intelligent alarms.

Widely used in residential, commercial, and industrial metering, they excel in challenging conditions like high sediment or freezing climates.

International certifications (MID, OIML R49, WRAS) ensure compliance and safety, while remote management and OTA upgrades reduce maintenance costs.
