Oxygen Flow Meter (Flowmeter) Column Analysis Report

Device Identification and Product Description

The product in the image is a mechanical flow meter (flowmeter) column used in medical gas systems to adjust the flow rate of the gas. This part, consisting of a transparent acrylic or similar hard plastic body, can be defined as a spare part/component of an oxygen therapy device or a wall-mounted oxygen outlet unit. The primary function of the device is to adjust and monitor the amount of oxygen gas (LPM) from the source in liters per minute.

Brand and Model Information

During a detailed examination of the product, no brand logo, model name, or distinctive mark indicating the manufacturer was detected on the body, adjustment knob, or connection points. The product appears to have a standard industrial design; however, definitive manufacturer information is not available in the image. Therefore, brand and model cannot be specified.

Areas of Use and Compatibility

This flow meter column is used in situations requiring medical oxygen therapy. Key areas of use and functions are as follows:

• Oxygen Therapy: Allows precise adjustment of the oxygen amount delivered to the patient.
• Device Integration: Can be integrated into oxygen concentrators, anesthesia machines, or hospital bedside units.
• Pediatric and Adult Use: Has the capacity to adjust within the range of 0 to 5 liters/minute (LPM). This low flow range is generally suitable for patients requiring low-dose oxygen or for pediatric use.

Technical Specifications and Measurement Scale

Technical data identified from the image are as follows:

• Gas Type: The “O2” marking on the lower part of the body indicates that this product is specifically calibrated for Oxygen gas.
• Flow Capacity: The scale has numbered increments from 1 to 5. The maximum measurement value is 5 units (likely 5 Liters/Minute).
• Indicator Type: Inside the transparent column, there is a black spherical float (ball) that moves upwards with gas flow.
• Flow Unit: Based on the inscriptions at the bottom, the unit is coded as “LPM” (Litre Per Minute) or “PM”.

Physical Condition and Cosmetic Examination

The general condition of the product appears to be very clean and new. Detailed physical analysis is as follows:

• Body: No cracks, yellowing, cloudiness, or deep scratches have been observed on the transparent plastic block. Numbers and scale lines are black, clear, and legible; there is no fading.
• Adjustment Knob: The black flow adjustment valve (knob) located at the top is clean. No wear or deformation is visible in its threaded structure or the metal/silver detail in the center.
• Internal Components: The black indicator ball inside the flow tube rests properly at the bottom; there are no signs of jamming.

Mechanical Components and Connection Points

The product is not just a flow tube but a ready-to-mount part. Mechanical details are as follows:

• Inlets and Outlets: On the rear of the product, there are two white, threaded connecting elements made of plastic or nylon material, which enable mounting to the device.
• Mounting Nuts: Metal (likely steel or nickel-plated) nuts, used to secure the product to a panel, are attached to the white connecting elements. No rust or corrosion is observed on these metal components.
• Gasket/O-ring: A black O-ring (gasket) providing sealing is present around the upper connection point.

Originality and Quantity Information

The image shows 1 unit of the flow meter column. Due to the absence of a brand label on the product, it is not possible to distinguish from the image whether it is a part of an original device or an aftermarket (equivalent) spare part. However, the material quality and print clarity indicate that it is manufactured according to industrial standards.

Evaluation Result

The examined oxygen flow meter (0-5 LPM) is physically undamaged, clean, and a complete set with mounting parts (nuts and fittings) attached. No cracks, breaks, or illegible text are present. No potential risk of malfunction is observed, and it is assessed to be ready for use once properly installed in the appropriate system.
