The FH-505 series ultrasonic flow meter is a high-precision, non-contact flow measuring device independently developed for water supply, drainage, and municipal water treatment scenarios. Covering mainstream ultrasonic flow meter types including transit-time and Doppler models, this integrated product balances standardized stable performance and flexible customized solutions. Adopting advanced ultrasonic signal processing technology, it eliminates mechanical moving parts, effectively avoiding wear, blockage, and leakage issues common in traditional flow meters. Designed for long-term continuous operation in complex water environments, the FH-505 series features wide measuring range, high adaptability, and low maintenance cost, serving as an ideal flow monitoring tool for municipal water projects and industrial water systems.
Product Features
Dual Measuring Principle Adaptation
The FH-505 series covers two core ultrasonic flow meter types: transit-time type for clean water media and Doppler type for sewage, turbid water with fine impurities. It can accurately measure flow velocity and cumulative flow of various water bodies, solving the measurement pain points of single-function flow meters with strong scenario compatibility.
Non-Contact & Loss-Free Measurement
With external clamp-on and non-intrusive structural design, the meter does not contact the measured fluid, no pressure loss is generated during operation, and no secondary pollution is caused to water quality. It completely avoids pipeline blockage and equipment damage, fully meeting the sanitary and safe measurement requirements of water supply and drainage systems.
High Precision & Stable Operation
Equipped with high-sensitivity ultrasonic transducers and intelligent signal filtering algorithms, the product achieves a measurement accuracy of ±0.5%~±1.0%. It can resist interference from pipeline vibration, water temperature fluctuation, and weak electromagnetic signals, ensuring stable and consistent measurement data for 24-hour long-term operation.
Low Maintenance & Long Service Life
Free of mechanical rotating and wearing parts, the overall failure rate is extremely low. The industrial-grade waterproof and dustproof shell adapts to outdoor and underground pipeline working environments. It requires no regular calibration and routine maintenance, greatly reducing later operation and maintenance costs for users.
Working Principle
The FH-505 ultrasonic flow meter adopts two mainstream ultrasonic measurement principles to adapt to different water quality conditions. The transit-time principle works for clean water media: two transducers installed on the pipeline transmit and receive ultrasonic pulses upstream and downstream respectively. Since the propagation speed of sound waves differs with and against the fluid flow, the meter calculates fluid velocity and volumetric flow by detecting the time difference of bidirectional signal propagation. The Doppler principle applies to turbid water and sewage containing suspended particles: ultrasonic signals are reflected by moving impurities in the fluid, and the equipment captures the frequency shift of reflected signals. The frequency shift value is linearly proportional to fluid flow velocity, realizing accurate flow measurement of impure water bodies. Built-in intelligent chips automatically identify water quality conditions and switch measurement modes to ensure universal applicability.

Application Fields
Focusing on water industry scenarios, the FH-505 ultrasonic flow meter is widely used in municipal water supply and drainage fields. In the water supply sector, it is applicable to tap water pipeline flow monitoring, water plant inlet and outlet flow statistics, and residential and commercial building water metering. In the drainage field, it stably measures the flow of urban domestic sewage, industrial wastewater, and rainwater drainage pipelines. It also supports flow data monitoring for water treatment processes such as sewage purification, circulating water regulation, and water resource dispatching, providing accurate data support for municipal water management, energy conservation and emission reduction, and pipeline operation monitoring.
Installation Method
The FH-505 series supports three flexible installation methods to adapt to different pipeline conditions and site environments. First, clamp-on external installation: transducers are fixed on the outer wall of the pipeline without pipe cutting or pipeline shutdown, featuring zero damage to the original pipeline, convenient and fast installation, suitable for finished pipelines and old project renovation. Second, insertion installation: drill and fix sensors on the pipeline wall, with stable signal transmission, suitable for large-diameter pipelines and long-term fixed monitoring scenarios. Third, inline installation: integrated measuring tube installation, with the highest measurement accuracy, applicable to high-precision metering scenarios of small and medium-diameter standard pipelines. All installation methods do not affect normal fluid transportation, and on-site debugging is simple with low technical threshold.
