Hongnuo (shenyang) General Machinery Co., Ltd. is one of the most reliable manufacturers and suppliers of portable ultrasonic flow meter for water in China. Welcome to buy high quality portable ultrasonic flow meter for water at competitive price from our factory. We also accept customized orders.

The HNF110-A Handheld Ultrasonic Flow Meter is a versatile, portable device engineered for non-contact flow rate and heat measurement, ideal for industrial, municipal, and HVAC applications like water treatment, petroleum, chemical processing, and heating/cooling systems. It operates by detecting ultrasonic signal time differences in flowing liquids, enabling accurate measurement without pipe cutting or fluid contact-eliminating clogging, corrosion, and leakage issues of traditional contact-type meters.

Equipped with clamp-on/bracket sensors (DN15-6000mm pipe range) and external temperature sensors, this meter supports fluid temperatures from -30℃ to 160℃, adapting to water, oil, chemicals, and other compatible media. It features a backlit LCD display (Chinese/English menus), 16-key operation, and robust data capabilities: 16000-group data logging, RS485/MODBUS communication, and compatibility with USB/Bluetooth printing. Flexible power options (rechargeable Ni-MH battery, alkaline batteries, external power) ensure up to 40 hours of continuous use, suitable for on-site inspections and long-term monitoring.

With IP68-rated sensors, anti-interference technology, and easy installation (V/Z mounting methods), the HNF110-A Handheld Ultrasonic Flow Meter delivers reliable performance in harsh environments. It offers linearity correction, zero-point calibration, and multiple flow units, meeting diverse measurement needs. Compact, durable, and maintenance-free, it's a cost-effective tool for engineers and technicians seeking portable, accurate flow and heat measurement-whether for field troubleshooting or routine industrial monitoring.

HNF110-A Handheld Ultrasonic Flow Meter Parameters
Specific Parameters	Value / Description
Measurement Principle	When an ultrasonic beam propagates in a liquid, the flow of the liquid will cause a slight change in the propagation time, and this change in propagation time is proportional to the flow rate of the liquid. At zero flow, the time required for the two sensors to emit and receive sound waves is exactly the same (the only technology that can actually measure zero flow), and when the liquid flows, the transmission time of the sound wave in the counter-flow direction is greater than that in the downstream direction. This relationship complies with the following expression: Where: θ: the angle between the beam and the direction of liquid flow M: the number of straight-line propagations of the sound beam in the liquid D: the diameter of the pipe Tup: propagation time of the sound beam in the positive direction Tdown: propagation time of the sound beam in the counter direction ΔT = Tup - Tdown
