Omron offers calibration and design assistance
Omron
Custom calibration and bypass design assistance
Omron Electronic Components is offering free custom calibration and bypass design assistance for flow sensing applications to customers whose requirements are not suited for off-the-shelf products.
Most of Omron's standard mass flow sensors are calibrated for air, except for the D6F-05N/L series, which has natural gas and propane calibrations.
For customers who want to measure other (non-corrosive) gases, the Omron factory team is able to assist with custom calibrations.
Each request is evaluated to determine if adequate engineering resources are available and to provide customers with lead-time for initial evaluation units.
Since the thermal properties and densities of different gases vary, the output curves for them will vary as well.
To optimise the output with some gases, minor circuitry adjustments to the sensors may be required.
Other gases are similar enough to air that a new output curve is all that needs to be provided.
Gases for which custom calibration is possible include argon, helium, heliox, carbon dioxide, nitrogen, natural gas, propane, nitrogen oxides, and oxygen.
A bypass set-up is a cost-effective means of measuring large flows with a low flow rate sensor.
To assist with the bypass design, Omron's engineering department will run a basic analysis utilising its Computational Fluid Dynamics (CFD) software to provide customers with a starting point for their design.
The process is started by providing some of the basic system parameters such as type of gas, flow rate range, Omron part number, main flow path dimensions, and the bypass tube dimensions.
It should be noted that the CFD analysis provides an estimate for ideal conditions that the customer should then test to verify or adjust based on actual conditions.
