Page 18: Operation
Bronkhorst® Operation After correct installation and taking all necessary safety precautions, the MI Series can be used to measure and/or control flow. Powering up After cleaning at high temperature, allow the instrument to return to ambient temperature before turning it on. -
Page 19: Valve Safe State
Condensed water increases the tube's mass, causing a density measurement error. Continuous purging of the housing interior with a dry, inert gas like Nitrogen can help prevent condensation. Contact your Bronkhorst representative for setting up an optimal purging configuration. 4.7.2 Cleaning temperature The MI Series may be cleaned with high temperature fluids. -

4.10 Adjusting zero point The zero point of a Bronkhorst® flow meter/controller (the measurement signal that indicates the absence of a flow) is factory adjusted at approximately 20 °C and atmospheric pressure (ambient conditions), with the instrument positioned upright. Under normal circumstances (i.e. when process conditions are constant), the zero point will remain stable. However, several factors might cause the instrument to develop a zero-stability error over time, causing it to detect a flow when actually there is none. -

Page 44: Troubleshooting And Service
To track down problems in the fluid system, depressurize the fluid system and disconnect the suspected unit from the process line. Dirt or clogging might be quickly detected by visual inspection on disassembled fluid connections. If you suspect leakage, do not disassemble the device for inspection, but contact your Bronkhorst representative for service or repairs. -
