Product Q&A

Q:Can this meter measure both cooling and heating energy in HVAC systems?

Yes. The HFU host can be integrated with an optional PT1000 temperature sensor (supporting both clamp-on and plug-in types). This transforms the device into a complete Ultrasonic Cooling and Heating Meter, perfect for energy management in building HVAC systems and thermal power plants.

Q:Our factory pipelines suffer from minor air bubbles and fluid impurities. Will it affect the accuracy?

The HFU series is designed to handle this challenge. Built with the latest 700K gate industrial-grade FPGA chip and advanced signal sampling, it features high bubble tolerance and can withstand intermittent bubbles or impurities for up to 5 seconds without interrupting your data.

Q:Is the sensor durable enough if I bury the pipe underground or install it in a wet environment?

Yes. While the main transmitter body is IP65-rated, the flow sensors themselves feature a fully sealed design with an IP68 waterproof rating. This means the sensors can be safely submerged or installed in highly humid and harsh outdoor environments.

Q:Can I connect this flowmeter to our central PLC/SCADA control room?

Definitely. For seamless industrial automation, the meter comes fully equipped with RS232/RS485 Modbus communication protocols, alongside standard 4-20mA analog output and 0 to 10 kHz pulse output.

Q:Am I allowed to power on or test the device immediately upon delivery?

Due to shipping carrier policies and technical safety, you can perform a visual and physical inspection (checking the housing, screen, and connections). For formal electrical testing or pipe installation, please contact our technical support team to guide you through the safe commissioning process.
