Weir Flow Meter Supplier: Built for Field Reliability
weir flow meter Supplier
Kingmach has been supplying weir flow meters as part of a broader geotechnical monitoring range for years. The focus isn't on selling a generic part; it's about matching the right structure to the channel conditions and flow range you're dealing with. Our meters go into irrigation networks, treatment facilities, and environmental monitoring stations where steady, repeatable readings matter more than glossy spec sheets. You'll find both standard V-notch and rectangular profiles, built in whatever material the site demands — stainless, PVC, or something else. Because we manufacture in-house, dimensional tweaks and integrated sensor brackets aren't special requests; they're part of the job. Most orders ship through regional distributors who handle local support, so you're not chasing a factory time zone for a replacement part.
Technical Detail
Configured around process stability, mold life, and long-term uptime.
A weir flow meter is a cost-effective way to measure open channel flow, relying on a well-documented stage-discharge relationship. Kingmach produces these devices with the same attention to construction and calibration you'd expect from a manufacturer focused on field instruments, not lab curiosities. The range covers common weir types: sharp-crested rectangular, V-notch for low flows, and trapezoidal for wider channels. Each unit is fabricated to your specified dimensions and can ship with a pre-attached stilling well or mounting plate if you need it. Materials are selected for the environment — stainless steel for corrosive or high-silt water, PVC for smaller agricultural channels, and occasional coated steel for budget-sensitive projects. Given that a weir's accuracy depends heavily on approach conditions and installation, we don't claim magic numbers. Instead, we provide downstream drawdown curves and recommended mounting guidelines so your site achieves the same accuracy as the engineering references you're following. Support doesn't stop at delivery: our distributors carry common spares and can walk your team through recalibration if the crest gets nicked or the channel geometry changes.

FAQ
Common technical questions
What types of weir flow meters does Kingmach manufacture?
We produce sharp-crested rectangular, V-notch (typically 90°, though other angles can be ordered), and trapezoidal weirs. Materials include stainless steel, PVC, and coated steel, with custom dimensions standard on all orders.
Can you integrate a level sensor or datalogger with the weir?
Yes. We often add mounting brackets for ultrasonic sensors or submersible pressure transmitters. If you already have a preferred datalogger or telemetry unit, we'll align the bracket pattern and connection interface to match.
How do I know which weir size and type is right for my channel?
Send us the expected flow range, channel cross section, and any site constraints like available head or upstream obstructions. Our application engineers will suggest the appropriate weir type and crest length based on standard guidelines (ISO 1438, for example). We don't charge for that consultation.
What's the typical lead time for a custom weir flow meter?
Lead times vary by material and complexity, but a standard stainless-steel rectangular weir usually ships within 3–4 weeks after final drawing approval. Large orders or specialized coatings may add time; we'll confirm a schedule before you commit.
Do you provide installation support or field calibration?
We provide detailed installation drawings and approach channel recommendations to help your crew. On-site support can be arranged through our distributor network, often at shared cost for larger installations. For recalibration after installation, we can walk you through the process remotely or supply a portable reference tool if needed.
