Hedland Flow Meter Website Navigation: Locating Certified CAD Models and Material Liners
Quick Answer: Engineers can find certified CAD models and material liner data on the Hedland flow meter website under the product series page. Open the Downloads tab for STEP, IGES, and PDF files. Filter by body material and seal option to match your fluid, pressure, and temperature.
What to Check Before Downloading a Hedland CAD File
Before you download any CAD model from the Hedland portal, confirm the full model number. The model number encodes body material, port size, seal material, and flow range. A H760 series meter with a 1 inch NPT port has a different drawing than the 3/4 inch BSP version. If you skip this check, you risk importing a drawing that does not match the quote. Most engineers skip this part because the website defaults to a standard aluminum body. In practice, a process engineer in Saudi Arabia learned this the hard way. The STEP file showed an aluminum housing while the actual meter was 316 stainless steel. That caused a mounting bracket clash during skid assembly.
Where Certified CAD Files Sit on the Product Page
On the Hedland product page, scroll past the product description and look for the Downloads or Resources panel. The Downloads tab holds dimensional drawings, 3D CAD files, installation manuals, and certificates. Certified CAD models usually carry a compliance note such as UL or CE in the file name or in the PDF cover sheet. If the file name includes a revision letter and a date stamp, the drawing is released for production. Do not rely on images from the gallery. Gallery images are often render files and may hide port details.
Material Liners and Wetted Parts by Model
Hedland variable area flow meters do not always use a separate liner. The body material itself is the primary wetted surface. Common body materials are aluminum, brass, 316 stainless steel, and polycarbonate. Seal options are Buna N, EPDM, Viton, and PTFE. The material liner data is not always on the main product page. You may need to open the Product Specifications tab or the Materials Compatibility PDF. Check the viscosity and temperature limits for each seal. For hot water above 70 Celsius, EPDM works better than Buna N. For phosphate ester fluids, Viton or PTFE is common. A paint manufacturer in Southeast Asia asked us to verify if a brass Hedland meter could handle MEK solvent. The website did not show a clear liner chart. We supplied the compatibility data before the order shipped.
Shortcuts for Hedland Material and Seal Selection
Use the series comparison chart. It lists port sizes from 1/4 inch to 3 inch, flow ranges up to 567 L/min, pressure ratings up to 350 bar depending on body material, and temperature ratings from minus 29 Ce
Common Gaps in the Hedland CAD Library
Some older Hedland models do not have a native STEP file. You may find a 2D PDF drawing but no 3D model. In that case, download the PDF and send it to your CAD team. The PDF has the overall length, port centerline, and mounting hole positions. Another gap is the lack of downloadable files for custom flow ranges. If your meter is calibrated for 0.5 to 5 L/min diesel, the standard drawings may not reflect the calibration tag position. Ask your supplier to confirm the drawing revision before you build the bracket.
Silver Instruments Support for Hedland Replacement and CAD Files
If the Hedland website navigation slows you down, we can pull the certified CAD file, material certificate, and seal chart for your specific model. Send us the full model number, your fluid type, flow range in L/min or GPM, viscosity in cP, and pipe size in DN. A process engineer in Saudi Arabia sent us a photo of a Hedland H760 label last month. We returned the STEP file, wetted material list, and a quote for a compatible stainless steel variable area flow meter within one working day. Our team at Silver Automation Instruments can also help you migrate from Hedland to a more cost effective meter with the same port size and calibration range.

FAQ
Where are certified Hedland CAD files located? Open the product page for your series and use the Downloads tab. Look for STEP or IGES files with a revision date and a compliance note.
Does Hedland provide material liner files? Yes, but the resource is usually named Materials Compatibility or Product Specifications. The file shows body and seal options for different fluids.
Which file format should I download for skid design? Use STEP for 3D CAD packages like SolidWorks or Inventor. Use PDF for dimensional checks and installation clearance.
Can I get certified drawings for custom flow ranges? You may need to request the certified drawing from the distributor or manufacturer. Standard downloads often show standard calibration only.
What if the Hedland website does not list my material or CAD file? Send the full model number and fluid details to Silver Automation Instruments. We can supply the missing file or quote a compatible replacement.
