Rossonix Co., Limited, established in 2011 and headquartered in Shenzhen, Guangdong, China, is a trading company that has steadily built its reputation as a dependable supplier of industrial testing and measurement instrumentation. With export business covering North America, Europe, South America, Oceania, the Middle East, and Asia, we understand the practical requirements of engineers and plant managers who need trustworthy tools for critical processes. The TSI 4040 Portable Digital Flow Meter is one of the practical solutions we offer for industrial gas flow monitoring, combining compact portability with reliable digital measurement technology. This instrument is ideal for field engineers, maintenance technicians, and facility managers who need a quick and clear picture of air and gas flow conditions across different work sites.
Product Overview
The TSI 4040 is a battery-powered, handheld digital flow meter designed for gas velocity and volumetric flow measurement in industrial environments. Its portable construction allows users to move freely around pipes, ducts, exhaust outlets, and ventilation openings while measuring flow parameters at the point of interest. The meter supports several measurement readings, enabling users to verify airflow performance and adjust systems when necessary.
Key Features at a Glance
- True handheld portability: The compact body and light weight make it easy to carry through large plants, crowded machine rooms, and elevated catwalks.
- Digital measurement reliability: Microprocessor-based electronics reduce manual reading errors and provide consistent results during repeated field tests.
- Multi-parameter readings: The instrument can display gas velocity, volumetric flow rate, and temperature values, depending on probe configuration.
- Backlit LCD display: The screen remains readable in dimly lit industrial rooms, basements, and covered outdoor stations.
- Durable industrial construction: The housing is designed to tolerate the normal vibration, dust, and moisture found in plant surroundings.
- Flexible data output: RS232 and USB options allow recorded readings to be transferred to computers for further analysis.
- Rechargeable power system: Built-in NiMH batteries can be recharged with an AC adapter, reducing the need for frequent battery replacement.
- Low-maintenance design: Modular probe and filter parts support simple replacement and routine care without special tools.
- User-oriented interface: A menu-driven layout gives quick access to measurement units, averaging modes, and hold functions.

Detailed Feature Overview
Reliable field measurements. The TSI 4040 uses a stable sensor platform and electronic signal processing to deliver repeatable flow readings during daily operations. Because it measures air velocity and flow rate without complicated tube connections, the meter shortens preparation time and allows technicians to sample multiple points quickly. The optional averaging function provides a more stable reading when the flow profile is turbulent or fluctuating.
Designed around the user. The operating menu is organized so that users can select engineering units, choose damping levels, and activate hold or average modes without long learning curves. The display presents the active reading in large digits and shows the selected unit clearly. Buttons are spaced for comfortable use even when the operator wears work gloves.
Data recording and transfer. For maintenance records, compliance checks, or commissioning reports, the optional RS232/USB connection allows the user to export measurement history to a computer. The companion software can help technicians organize site data and build simple trend views. Users who prefer manual record keeping can still read values directly from the LCD and note them on inspection forms.
Built for continuous industrial service. Temperature changes, dust, minor impacts, and regular handling are common in industrial workplaces. The TSI 4040 enclosure and probe structure are selected to handle these conditions, and the complete unit remains compact enough for daily transport from one work area to another. This combination of ruggedness and portability makes it suitable for plant maintenance teams, third-party testing services, and commissioning engineers.

Frequently Asked Questions
Q1. Does the meter come with a probe, or do I need to buy it separately?
The probe is normally included in the standard package. Different probe lengths and sensor variants can be arranged as optional extras according to the measurement point and duct size. If your application involves high ducts or hard-to-reach locations, please tell our team so that we can recommend a suitable probe configuration.
Q2. Can I use it for gases other than air?
The instrument is commonly used for air and neutral industrial gas flow monitoring. For special gas mixtures, please contact our sales engineers with your gas type and expected velocity range. A modified or recalibrated unit can be discussed based on project requirements.
Q3. How often does the unit need calibration?
Calibration intervals depend on the working environment and internal quality rules. Factory calibration before shipment can be arranged, and recertification service is available upon request. Periodic calibration checks are recommended for sensitive applications, in line with standard industrial practice.
Q4. Is the display readable outdoors?
The LCD includes a backlight, which supports reading in normal indoor and outdoor conditions. Where direct sunlight is involved, a shading hood or simply adjusting the meter angle usually provides a clear view.
Q5. What kind of battery does it use?
The meter uses a rechargeable NiMH battery pack and can be operated with an AC adapter. The removable design allows a spare charged pack to be fitted quickly when extended field work is required.
Q6. Can I connect the flow meter to a PC?
Yes, optional RS232/USB accessories and companion software allow recorded data to be exported for further analysis. Please specify whether you need this connection kit when placing your order so that all necessary cables and drivers are included.
Q7. How do you support customers after delivery?
