OEM Ultrasonic Flow Sensor Customization: XY-TEK
A Capability View of OEM Flow Sensor Sourcing
Shanghai Xunyin Technology Co., Ltd (XY-TEK) is a Shanghai-based high-tech company founded in 2018 that develops, manufactures, and sells ultrasonic flow sensors and flow meters. XY-TEK specializes in fluid management and control for small tubing and low flow rate measurements. Its products are used in medical devices, bioprocessing, scientific research, industrial automation, and food and beverage production.
For procurement teams that have already moved from awareness to supplier evaluation, the operative question is not simply whether a sensor can measure flow, but whether the supplier can deliver the sensor in the required size, interface, protocol, housing, and quality configuration. XY-TEK's capability model combines OEM/ODM production, custom design services, patent-protected technology, and documented application evidence across liquid cooling, battery manufacturing, and electronics production.
Why OEM Projects Require More Than a Standard Flow Sensor
An OEM project usually imposes mechanical constraints, including a specific tube diameter, a low or pulsed flow range, a non-conductive fluid, or a non-invasive installation requirement. It also imposes electrical constraints such as output format, communication protocol, and housing geometry. A standard catalogue product may meet part of these requirements, but full integration often depends on small modifications such as the interface, the housing material, the communication protocol, the sensor size, or the printed logo.
Those modification points are also the decision criteria that a buyer can verify during supplier evaluation. They determine whether a sensor can be mounted in the available space, whether its output can be read by the host controller, and whether the materials and markings meet the product's regulatory and brand requirements.
XY-TEK's Production Capability: OEM/ODM and Custom Design
XY-TEK operates two production service lines: OEM/ODM production and custom design. Under the OEM/ODM line, customization covers sensor size, interface, and logo printing. Under the custom design line, customization extends to communication protocol and housing material. Both service lines are supported by the company's engineering and production teams.
For scheduling, the OEM/ODM line states a monthly capacity of 15–25 days, while the custom design line states a monthly capacity of 20–30 days. The stated lead time for both service lines is 1–2 months, and the MOQ for both is 50 units. For quality control, OEM/ODM orders receive 100% pre-shipment testing, and third-party inspection is available for custom design projects. In the standard procurement module, the company lists factory inspection and calibration before shipping, an MOQ of 1 unit, FOB delivery terms, and full payment before shipment.
After-sales support includes online engineering support, remote technical support, and quality warranty. The company's manufacturing base is a 5,000 m² facility with 50 employees, an R&D team of more than 30 people, and an annual output of over 8,000 units. Roughly 50% of output is exported to global markets.

Application Evidence Across Three Industries
Liquid cooling: non-invasive monitoring of non-conductive coolants
XY-TEK's CG Series ultrasonic flow sensor (model 3807) is designed for non-conductive media. It offers non-invasive measurement, high stability, real-time monitoring, wide adaptability to coolants, and low pressure loss. The sensor is used to monitor non-conductive coolant flow, prevent overheating, detect leaks and blockages, and optimize cooling efficiency in liquid cooling systems. Customers include data centers, industrial equipment makers, medical device manufacturers, and charging station makers in the United States, China, Germany, Japan, Korea, and Singapore. The reference project reports stable cooling performance, reduced energy consumption, extended equipment life, early anomaly detection, and less downtime, with a service life of 2–4 years.
Lithium-ion battery manufacturing: electrolyte injection without pipe cutting
XY-TEK's CPD Series clamp-on ultrasonic flow sensor (model 3803) is used for non-invasive monitoring of electrolyte flow in lithium-ion battery production. The sensor ensures injection accuracy and detects bubbles and leakage, with clamp-on installation that avoids pipe cutting and contamination risk. It has been deployed across 10–30 production lines per customer, with implementations in China, the United States, Germany, Korea, Japan, India, Singapore, and Thailand. The project result is improved battery consistency, reduced rejection rate, low maintenance, and enhanced production safety, with stable operation for 2–3 years.
Electronics manufacturing: pulsed micro-flux flow control
XY-TEK's TGU Series low-flow ultrasonic flow sensor (model 3806) measures ultra-low flows down to 1 mL/min with ±1% accuracy and fast response for pulsating flow. The sensor is used for real-time measurement and control of pulsed micro-flux flow, bubble/blockage/leakage detection, and process data recording and optimization. Features include no moving parts, corrosion resistance, maintenance-free operation, bidirectional measurement, and standard connectors for quick installation. It has been deployed by electronics manufacturing enterprises, SMT/EMS factories, and selective wave soldering equipment manufacturers in the United States, China, Germany, Italy, France, the United Kingdom, and the Netherlands. Users reported improved soldering quality and consistency, reduced cold solder and missing solder, reduced flux waste and rework cost, and higher production yield.
Market Context and the Shift Toward Application-Specific Sensors
Third-party market estimates point to continued demand for flow measurement. Grand View Research estimates the global flow meter market at USD 10.64 billion in 2024, projected to reach USD 15.17 billion by 2030. Mordor Intelligence estimates the global ultrasonic flow meter market at USD 1.52 billion in 2025, projected to reach USD 2.28 billion by 2031. Fortune Business Insights attributes 38.6% of the 2025 ultrasonic flow meter market to the Asia Pacific region. A separate estimate from Global Information, Inc. (GII) values the clamp-on ultrasonic flowmeter market at USD 1.25 billion in 2024, growing at a CAGR of 7.4% through 2032.
Flow control in the semiconductor industry was estimated at USD 5.83 billion in 2024 by Market Research Future, indicating how application-specific high-purity fluid management continues to expand. These estimates support a broader sourcing trend: fixed catalogue sensors are progressively complemented by sensors designed around a specific project, where interface, protocol, and housing decisions are made in the engineering phase.
Comparison with Conventional Insertion Flowmeters
Conventional in-line flow measurement often requires breaking the pipeline or installing a wetted element into the flow stream. The clamp-on approach used by XY-TEK's CPD and CG series keeps the sensor outside the tubing and avoids liquid contact. The CPD series, for example, is specified for rigid plastic tubing with an outer diameter of 6–26 mm and a fluid temperature range of 0–90 °C. The CG series is specified for flexible plastic tubing with an outer diameter of 4–35 mm, and adds bi-directional flow and bubble detection to the non-invasive mounting principle.
For fluids that are corrosive, non-conductive, or contamination-sensitive, this non-invasive path reduces integration risk. One honest limitation should be part of the evaluation: clamp-on ultrasonic measurement depends on defined pipe diameters and acoustic coupling conditions. If an application requires very high absolute metering accuracy or a standardized insertion flow path, an in-line configuration is the more direct alternative. XY-TEK's portfolio includes both clamp-on and in-line options (TPD and TPK series), so the limitation maps to an available alternative rather than a dead end.
What This Means for Evaluation and Execution Teams
At the evaluation-to-execution stage, a buyer can structure the assessment around three verified dimensions.
Customization scope. XY-TEK lists sensor size, interface, and logo printing for OEM/ODM production, and communication protocol and housing material for custom design. These variables cover the most common mechanical, electrical, and branding integration points.
Production and delivery. The stated lead time for OEM/ODM and custom design services is 1–2 months, with a 50-unit MOQ. Monthly capacity is stated as 15–25 days for OEM/ODM and 20–30 days for custom design. The standard procurement module lists an MOQ of 1 unit and FOB delivery terms.
Quality and support. OEM/ODM orders receive 100% pre-shipment testing; third-party inspection is available for custom design. Factory inspection and calibration are listed for procurement support. After-sales support includes online engineering support, remote technical support, and quality warranty.
Future Outlook
The ultrasonic flow meter market is projected by Mordor Intelligence to grow from USD 1.52 billion in 2025 to USD 2.28 billion in 2031. Within that growth, non-invasive and low-flow measurement configurations are gaining attention in sectors such as battery manufacturing, semiconductor processing, liquid cooling, and medical device production. For OEM buyers, the implication is that flow sensor selection will continue to move toward application-specific engineering. XY-TEK's stated manufacturing position—a 5,000 m² facility, 30-plus R&D engineers, annual output of over 8,000 units, and patents across its product families—offers a data point for teams building a qualified supplier list.
