YEX-HY-RFMS-01 Radar Flow Meter Sensor

Non-contact velocity and level monitoring for open-channel flow measurement.

YexSensor YEX-HY-RFMS-01 combines radar velocity measurement and radar water level measurement for open-channel flow applications. It helps integrators build a more maintainable monitoring system where submerged sensors are difficult to install or maintain.

Core Technical Advantages

• 24.00 GHz radar velocity sensing supports stable surface velocity measurement without direct water contact.

• 76-81 GHz radar level measurement provides high-resolution distance feedback for flow calculation.

• Non-contact installation reduces risks caused by silt, debris, corrosion and sensor fouling.

• RS485 Modbus RTU output enables direct connection to PLC, RTU and remote monitoring platforms.

Application Scenarios

• Open-channel flow monitoring

• River and flood discharge monitoring

• Urban drainage network monitoring

• Irrigation canal flow measurement

• Hydrological station upgrades

Technical Performance Parameters

Installation and Wiring Guide

Install the sensor above the channel and align the sensing direction with the water flow. The preferred position is near the channel center or a representative flow section with a stable water surface.

Wiring note: Use DC 10-30V power and RS485 A/B communication wiring. Keep power and signal cables away from high-voltage or high-current lines.

Maintenance and Commissioning Guide

Inspect the mounting bracket, cable entry and radar window periodically. Verify flow section parameters when the channel profile changes.

Frequently Asked Questions

Q1: Does the sensor need to be placed in water?

A1: No. The radar flow meter is installed above the channel, reducing fouling and maintenance.

Q2: What data can it output?

A2: It can provide velocity and water level data for flow calculation and remote monitoring.

Q3: Is it suitable for dirty water?

A3: Yes. The non-contact structure is well suited to drainage, rivers and channels with silt or debris.

Q4: Can it communicate with SCADA?

A4: Yes. RS485 Modbus RTU supports PLC, RTU and SCADA integration.

Q5: What affects velocity accuracy?

A5: Installation angle, water surface condition and selected flow section are key factors.

Q6: Can it be used outdoors?

A6: Yes. It is designed for hydrology and outdoor monitoring environments.

Q7: Does it measure full-pipe flow?

A7: It is mainly intended for open-channel or non-contact surface flow applications.

Q8: How should it be commissioned?

A8: Confirm mounting angle, channel parameters, communication address and Modbus register reading.

Summary

YEX-HY-RFMS-01 is a strong fit for non-contact open-channel flow projects where stable measurement, lower maintenance and Modbus-based integration are priorities.
