The Sage thermal mass flow meter requires little maintenance, aside from periodic inspection of the sensor to ensure it has no particulate buildup when in unclean industrial environments.

Thermal Mass Flow Meter Cleaning

While the sensing element is rather 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. A soft brush may be used to apply the cleaning agent gently to avoid damaging the sensor elements (RTDs).

If the user determines that disassembly is required to clean the meter call Sage Metering Customer Service. Please understand that it is usually recommended that the meter be returned to the factory for this level of cleaning as well as repair and recalibration. This 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 at a “no-flow” situation and compare it to the initially reported “zero flow” value. This value is recorded in the meter’s Certificate of Conformance and/or 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.
