The Sage thermal mass flow meter requires little maintenance, aside from periodic inspection of the sensor (when in unclean industrial environments) to ensure it has no particulate buildup.
Thermal Mass Flow Meter Cleaning
While the sensing element is somewhat resistant to dirt and particulate buildup, in some industrial environments that are extremely dirty, it may become necessary to clean the sensor at times. If this is the case, first, before cleaning, always remove the power from the meter. When cleaning, always use a mild detergent or a non-corrosive solvent to eliminate particulate buildup. Apply the cleaning agent gently with a soft brush to avoid damaging the sensor elements (RTDs).
If disassembly is required to clean the meter, call Sage Metering Customer Service. Please understand that we usually recommend returning the meter to the factory for this level of cleaning and repair and recalibration. By doing so, it is the most cost-effective and reliable option to ensure your meter remains accurate.
Sage In-Situ Calibration Verification
The Sage Prime thermal mass meter has continuous diagnostics with raw calibration milliwatts (mW) consistently shown in the upper left-hand corner of the meter’s display. At any period, the user can check this reading in a “no-flow” situation and compare it to the initially reported “zero flow” value. This value is on the meter’s Certificate of Conformance and the flowmeter’s data tag. This diagnostic practice, which is known as the Sage In-Situ Calibration Verification, not only tests the sensor’s performance and the “live zero” calibration point, but it also confirms that the sensor is clean. This Sage unique method provides a means to validate the meter’s performance and verifies that there is no drift or shift, and eliminates the necessity for yearly factory calibrations. This simple field diagnostic procedure can confirm that the sensor is free of contamination, even without even inspecting it.
