Key features

Non-Contact Clamp-On Design: Transducers clamp externally on pipes, ensuring non-fouling operation and easy installation without cutting pipes.

Wide Pipe Compatibility: Supports pipe sizes from 15mm to 6000mm and materials including steel, stainless steel, PVC, copper, and FRP.

Versatile Liquid Application: Measures water, sewage, acid/alkali, alcohol, beer, and oils with turbidity less than 10000ppm.

Bi-Directional Flow Measuring: Capable of measuring net flow and heat in both directions, accommodating complex pipeline systems.

Long-Term Data Recording: Automatically records totalizer data for the last 64 days/months/5 years and power-on/off events.

Flexible Output Options: Provides 4-20mA/0-20mA analog output, frequency signal, relay output, and RS485 serial port.

Low Maintenance Cost: No moving parts ensure maintenance-free operation, reducing long-term operational costs significantly.

AI-Powered supplier vetting

SummaryThe supplier is identified as a combined company with manufacturing, export, service, quality-control, and R&D capabilities. Evidence shows documented procedures for corrective actions, customer complaints, supplier assessment, and R&D design controls. It provides overseas installation, debugging, maintenance, repair, and training, supported by overseas agents or branches, but has no overseas warehouse or showroom. R&D capabilities include recent product development, ODM/OEM services, 3D design, multiple engineering software tools, and documented design verification activities; however, no SDK is available. Production evidence includes four production lines and stated annual capacities of 500,000 level sensors, 500,000 pressure sensors, and 300,000 flow meters, with lead times within 15 working days in both peak and off-peak seasons. No explicit certification, financial-strength evidence, or named customer cases is provided.

Supplier typeThe supplier is explicitly classified as a combined company rather than an offshore company. Its listed offerings cover manufacturing, export trade, service, quality control, R&D, and sustainable development capabilities, indicating a broad integrated supplier profile.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and customer complaints. It offers overseas debugging, maintenance, repair, training, and equipment installation, and operates through overseas agents or branches; however, it has no overseas warehouse or showroom.

R&D capabilityThe supplier reports new product development during the past year, ODM services, 3D software design, and R&D tools including CAD, SolidWorks, Altium Designer, and LabVIEW. It also maintains design input, output, review, verification, and validation documents, although no SDK is available.

Production capacityThe supplier operates four production lines and reports annual capacities of 500,000 level sensors, 500,000 pressure sensors, and 300,000 flow meters. It lists specialized production and testing equipment, with lead times stated as within 15 working days in both peak and off-peak seasons.

Customization capabilityThe supplier explicitly provides customization from samples, customization from designs, full customization, minor customization, and flexible customization, together with 3D design and ODM services. These records support broad product customization capability.

Product Q&A

Q:What mounting methods are supported for the transducers?

The transducers can be mounted in V-method (sound traverses pipe twice), W-method (sound traverses four times), or Z-method (sound crosses once on opposite sides), depending on pipe and liquid characteristics.

Q:Which pipe materials and sizes are compatible?

It supports pipe sizes from 15mm to 6000mm. Compatible materials include steel, stainless steel, cast iron, cement, copper, PVC, aluminum, and FRP.

Q:What types of liquids can be measured?

It measures liquids that can transmit ultrasonic signals uniformly, such as water, seawater, industrial sewage, acid/alkali liquids, alcohol, beer, and various oils, with turbidity less than 10000ppm.

Q:What communication protocols and outputs are available?

It supports MODBUS, M-BUS, Fuji extended protocol, and other factory protocols. Outputs include 4-20mA/0-20mA current, frequency signal (1-9999HZ), relay output, and RS485 serial port.

Q:Is the flow meter bi-directional?

Yes, it supports bi-directional measuring, allowing for net flow and heat measurement in both directions.
