SEGMENsensor U12 compact clamp-on ultrasonic flow meter, the base model for private-label supply

Key facts

SEGMENsensor supplies clamp-on ultrasonic flow meters as private-label (white-label) products: the meter is built and calibrated in our Shenzhen factory and delivered with your brand on the faceplate and nameplate, an English menu and neutral packaging, so you sell it as your own model.

The U12 one-piece meter fits DN15–DN65 pipes and measures 0.03–10 m/s, with ±2% accuracy (±1% after calibration).
Outputs are any two of 4–20 mA, RS485 Modbus, OCT pulse and one relay; LoRa or 4G can be customised.
Supply is 10–24 V DC, protection IP65, and the sensor cable is 2 m as standard (up to 5 m).
Each unit can ship with a factory calibration report, and every carton is photographed before dispatch for your approval.
Qualification samples of 1–5 pcs ship in 5–7 days; production lead time and order quantity are confirmed with the quotation.

Transcript

Looking for a clamp-on ultrasonic flow meter to sell under your own brand? Here is how SEGMENsensor private-label supply works. The usual base model is the U12 one-piece meter. It clamps straight onto DN15 to DN65 pipes, with no pipe cutting, and it is CE and UKCA marked. From the datasheet: velocity from 0.03 to 10 m/s, and ±2% accuracy, or ±1% after calibration. Choose any two of 4–20 mA, RS485 Modbus, pulse or relay. Power is 10–24 V DC, and the housing is IP65. On a private-label meter, we print your logo, colours and model code on the faceplate, and your data on the nameplate. The display menu is in English, with other languages on request for your market. Every private-label meter can ship with a factory calibration report, with three-point calibration available. Neutral export cartons carry no maker marks, and we photograph each packed batch for your approval before it ships. Each meter is tested on the water flow test line before it is packed. A project runs in six steps: your specification, an artwork proof, branded samples, order confirmation, production and calibration, and finally packed-batch approval. Branded qualification samples of 1–5 pieces ship in 5–7 days. Production lead time and order quantity are confirmed with the quotation. Send your specification and brand files through segmensensor.com, and our engineers will reply within 24 hours.

Private label

What can be customised on a private-label meter?

The faceplate, nameplate, display menu language, packaging, calibration paperwork and output combination can all be set to your brand. The table shows what is standard and what is confirmed per project.

Models

Which clamp-on models can be private-labelled?

Any model in the range can be supplied under your brand. Small-pipe buyers usually start with the U12 or U13 one-piece meters; the U10S and U20 cover larger pipes and portable surveys.

SEGMENsensor U12 compact clamp-on ultrasonic flow meter clamped on a vertical pipe, with CE and UKCA marks — U12 clamped on the pipe — the standard version shown before private-label artwork is applied.

U12: the usual base for a small-pipe private-label range

The U12 clamps directly onto DN15–DN65 pipes with the transducers built into the housing, so there is no separate converter to mount and no pipe cutting. The front faceplate carries the brand, model code and keypad graphics — this is the area replaced with your artwork. Cable connections are at the top of the housing, and the meter is CE and UKCA marked.

U12 maximum flow by pipe size

Pipe size	DN15	DN20	DN25	DN32	DN40	DN50	DN65
Upper flow limit (L/min)	60	100	200	300	400	600	1000

Values from the SEGMENsensor U10–U20 datasheets. Minimum measurable pipe inner diameter for the U12 is 12 mm. Full specifications: clamp-on ultrasonic flow meters and portable clamp-on flow meter.

Process

How does a private-label project run?

It runs in six steps: specification, artwork proof, qualification samples, approval, production and packed-batch approval before dispatch.

Send the specification

Model, pipe sizes, outputs, supply voltage, cable length, medium temperature and expected annual volume.

Approve the artwork

You send logo, faceplate and nameplate files; we return a proof of the faceplate, nameplate and carton for sign-off.

Test the samples

Qualification samples of 1–5 pcs ship in 5–7 days with your branding and calibration reports.

Confirm the order

After sample approval we confirm production lead time, order quantity and packing with the quotation.

Production and calibration

Each meter is tested on our water flow test line and calibrated before packing.

Packed-batch approval

We photograph the packed batch for your approval, then ship by courier or to your forwarder.

FAQ

Private-Label Clamp-On Flow Meters — Frequently Asked Questions

Answers for instrument brands and distributors planning a private-label range.

Can you put our brand on the flow meter?

Yes. We print your logo, colours and model code on the faceplate and your data on the nameplate. You send the artwork and we return a proof for approval before samples are built.

Is the packaging neutral?

Yes. Private-label meters ship in a neutral export carton suitable for international courier, with no SEGMENsensor marks and no Chinese labels on the product or packaging. We can photograph the packed batch for your approval before dispatch.

Which display languages are available?

The standard private-label menu is English, with no Chinese text on the display. Other menu languages can be added on request for your target market.

Do the meters come with calibration reports?

Yes, on request each unit ships with a factory calibration report, and three-point calibration is available. The U12 is specified at ±2%, or ±1% after calibration.

How many units do we need to start?

You can start with 1–5 branded qualification samples, which ship in 5–7 days. Production lead time and order quantity are confirmed with the quotation and planned around your annual volume.

What certifications do the meters carry?

The U10, U10S, U11, U12, U13 and U20 clamp-on meters are CE and UKCA marked. Certificate copies are available on request with the quotation.
