Supply & OEM
Water Meter Manufacturer and OEM Supplier
Shandong Chenshuo Instrument builds water meters from DN15 to DN300: prepaid STS, smart AMR, ultrasonic, mechanical multi-jet, Woltman bulk and electromagnetic. The table below is the list we can quote against — every row is a model we hold current specifications for. Anything outside that list is a custom build, and you hear that in the first reply rather than waiting on a price we cannot hold.

Where We Draw the Line
What We Say Yes To, and What We Don't
Every capability page says yes to everything. This is the part that helps when you compare three.
What we can quote straight away
Short answers, no caveats buried in the small print.
- Any combination in the table above — specifications and pricing are current
- Like-for-like replacement: same DN, same lay length, no pipe work
- Communication to suit: 4G, NB-IoT, LoRaWAN or M-Bus
- Your name and model number on the dial, plate and packaging
- Split shipments if your site takes delivery in stages
What we will tell you no about
Better to lose the enquiry at the start than the order at the end.
- Sizes outside the table — custom build only, and you hear it first
- Prepaid or valve control above DN65 — not in the current range
- Hot water and special media — no product line for it, so no promise
- Any parameter we have not verified — left out rather than filled in
How You Can Check Us
Before You Commit to a Container
The means to check us yourself — all of it startable today.
Ask for a sample first
Fit one, test it on your own bench, pull it apart if you want to. The bulk order follows your result, not our description of it.
Walk the line on video
We take you through assembly and the calibration bench on a live call. Ask for whatever angle you want — it is a factory, not a studio.
Send your own inspector
SGS, BV or your own engineer. We work to their checklist rather than ours, and we would rather they find a problem here than at your port.
Read the test report
Calibration and test records filed against your order, not a generic certificate.
Check the paperwork
Packing list, invoice, origin certificate, bill of lading — in the form your broker expects.
Start with a split order
Take a small batch, run it for a season, then scale up. It costs a little more per unit and removes most of the risk from the first buy.
How an Order Runs
Seven Steps, No Black Boxes. You always know which step you are on.
You send the specification
DN, quantity, medium, communication, destination. The six things listed further down this page are enough for us to work from.
What you send: size, connection type, quantity, medium, communication, destination country.
We check coverage
We check your combination against the table and say plainly: stock build or custom.
What you get: a straight yes, a no, or a custom-build answer with the conditions attached.
Quotation with the conditions attached
Price moves with quantity, size, comms and destination. Price and conditions in one message.
What you get: a price, and the four things that shape it — quantity, configuration, destination, schedule.
Sample or drawing approval
For large sizes and tendered work, you approve a unit or a drawing before we build the rest. This is where a mistake is cheap to fix.
What you get: a physical unit or an approved drawing to sign off before production starts.
Production scheduling
Your order goes into the schedule with a date, not an estimate. If something shifts it, you hear about it then rather than in the last week.
What sets the date: order size, communication option fitted, and current factory load.
Inspection and calibration
Meters are calibrated and inspected before packing. Your inspector is welcome to attend — their checklist, not ours.
What you get: calibration and test records that travel with your batch.
Packing, documents, shipment
Packed for the journey, documented for your customs broker, and shipped whole or in stages depending on what your site can receive.
What you get: packing list, commercial invoice, certificate of origin, bill of lading.
OEM & Customisation
What We Can Change for You
Want your name and your protocol? Say so at enquiry — easier to build in than add on.
Your name on the meter
Dial face, nameplate, model numbering and packaging under your brand, so the unit arrives looking like it came from you.
Your protocol and platform
4G, NB-IoT, LoRaWAN or M-Bus, configured to report into the platform you already run rather than one you would have to adopt.
Your packing and documents
Carton markings, manuals in your language, and export paperwork laid out the way your customs broker expects to receive it.
What We Need From You
Six Things and We Can Quote
These six decide price, lead time and whether we can take the order. Send them, get a number back.
Size and connection
DN, threaded or flanged, and which flange standard
Quantity
Total units, and whether delivery is in one lot or staged
Medium and temperature
What is flowing through it, and how hot
Communication
4G, NB-IoT, LoRaWAN or M-Bus — and the platform it must report to
Destination country
Drives approval requirements and the shipping documents
Valve or prepaid
Whether you need remote shut-off or prepaid control
Miss one and we ask, which costs a day. Destination and communication change the answer most.
Before You Enquire
Questions Buyers Ask First
Are you a manufacturer or a trading company?
We build them. The table above is the clearest answer we can give — it lists model and size combinations at a level of detail a trading company cannot produce, because a trader does not know which sizes the factory actually holds tooling and calibration for. If you want to confirm it rather than take our word, ask for the video walk-through or send your own inspector.
What is your minimum order quantity?
It depends on the model and the size — a DN20 household meter and a DN300 bulk meter are not the same conversation. Rather than publish a figure that would be wrong for half the range, we tell you the MOQ for your specific combination in the first reply. Send the DN and the quantity you have in mind and we will work from there.
Can you put our brand on the meters?
Yes — dial face, nameplate, model numbering and packaging can carry your brand. Tell us at the enquiry stage so it is built in rather than added afterwards. We will confirm exactly how far it goes for the model you are ordering.
Which certifications do you hold?
Approval is three separate things and they do not substitute for one another: legal metrology type approval (whether the meter can be used for billing in that country), a product or quality mark (whether buyers and tenders accept it), and an import clearance certificate (whether the shipment is released at port). Which of the three you need, and which we hold, depends on your market. Tell us the destination country and the application, and we will confirm what applies there and where we currently stand on each.
How long is delivery?
It varies with order size, the communication option fitted and current factory load — which is why we do not print a number here. Once the specification is confirmed you get a date you can hold us to, and if it moves you hear about it when it moves, not in the final week.
Send the DN and the Quantity
Those two tell us most of it. You get the models that cover the combination — or a plain custom-build answer.
