Ultrasonic flow meters
Non-contact flow for open channels, flumes and bypass lines
Ultrasonic meters measure flow without mechanical contact, by transit time, Doppler or level over a primary device. They suit STP bypass lines, Parshall flume outlets and gravity drains, where low maintenance and accuracy both matter.
SYZE pairs ultrasonic sensors with rugged RTUs, solar-compatible telemetry, dashboards and compliance reporting, installed to CPCB / HSPCB guidelines.
Ultrasonic level over a flume
System architecture
- Sensor
- Siemens SITRANS Probe LU240 ultrasonic level probe at the flume throat
- Flume
- FRP Parshall flumes to ISO 9826, with calibrated throat and head-discharge tables
- RTU
- SYZE industrial RTU with RS-485, local memory and remote updates
- Telemetry
- 4G Modbus to MQTT / HTTP uplink with buffer-and-resume
- Dashboard
- Real-time flow conversion, trends, overflow detection and bypass flagging
