کارتریج جایگزین برای فلومتر AGILENT مدل G6692A

The ADM Flowmeter flow cartridge (G6692A) contains all the flow measurement
components that are subject to periodic calibration. This unique feature allows the
flowmeter to be recalibrated remotely by replacing this low-cost component. Testing
has shown that the flow cartridge will hold its calibration, within the published
tolerances, for a period greater than one year under heavy use. However, the time
between manufacturing date and the date that the cartridge is first used cannot
be predicted. This document demonstrates that the flow cartridge can hold a valid
calibration for a period greater than three years when stored under the expected
conditions.
The flow cartridge is electromechanical in design. Increasing the temperature
increases the stress on the electrical and mechanical components, leading to
premature failure compared to normal temperature conditions. We tested the
performance of the flow cartridge stored for a prolonged period at a temperature
higher than normal. The resulting data were used to calculate the minimum
expected storage lifetime for the flow cartridge when stored within the expected
storage temperature of less than 30 °C
