OEM & custom development
When Standard Flow Meters Do Not Fit Your Application
If a standard flow meter does not fully match your application, we can review the required connection, range, materials, output and other specifications and discuss a custom solution.
Configuration
Review connection type, flow range, materials, output and other application-specific requirements.
Development from Your Requirements
Share your drawing, sample or technical specification so we can review feasibility before development.
Manufacturing & testing
From production to calibration
Flow meters are machined, assembled, then calibrated and tested before shipment.
Production
Components are machined and prepared according to product requirements before assembly.
Assembly
Flow meters are assembled at dedicated workstations, with components checked during the assembly process.
Calibration & Testing
Finished meters are calibrated and functionally tested on flow test lines before shipment.
