Mass flow controller MFC2000 User Manual
4. Installation
Do not open or alter any part of the product which would lead to malfunction and irrecoverable
damage. It will also forfeit the terms of the warranty and cause liability. Check the application
requirements and verify whether they are matching to the product specifications, in particular the
gas compatibility and pressure/temperature ratings for safety reasons.
The product at the time of shipment is fully inspected for its quality and meets all safety requirements.
Additional safety measures during the installation should be applied. This includes, but is not limited
to the leakage verification procedures, standard EDS (electrostatic discharge) precautions, and DC
voltage precautions. Other tasks such as calibration, part replacement, repair, and maintenance
must only be performed by trained personnel. Upon request, the manufacturer will provide
necessary technical support and/or training for the personnel.
There are no preferred space directions for the installation. However, since the products are
calibrated at the horizontal installation, vertical placement of the product may incur some minor
offset if the products are calibration with a large dynamic range. When this happened, please apply
the reset offset function described in this manual (Section 5) to ensure the offset is properly zeroed.
The flow direction should be aligned with the arrow mark on the meter body. If the flowing fluid may
have particles or debris, a filter is strongly recommended to be installed upstream of the meter.
The products have four mounting holes (threaded) located at the bottom of the products, refer to
Section 3.3.
The connection pipes or tubes should be clean and free of foreign materials. Gas compatibility must
be observed for the proper performance of the products. To ensure there is no gas instability, the
pipe or tube diameter should be matching with that of the product. Avoid installing pipes or tubes
with a smaller diameter than that of the products, otherwise, it may create a strong flow instability
in particular at the laminar flow range, and result in significant inaccuracy of the measurements.
If another valve or pressure regulator must be installed closer to the products, please keep them at a
distance of at least 15 times the pipe diameter from the products.
Please follow the following steps to complete the installation:
a) Upon opening the package, the product's physical integrity should be inspected to ensure no
visual damage.
b) Do not install this product in an environment with excessive vibration, noise, and or
c) Before installation of the product, please ensure that the pipe debris or particles or any other
foreign materials are completely removed.
d) Close the upstream valve, if any, completely.
e) During installation, please make sure no foreign materials (such as water, oil, dirt, particles, etc.)
enter the installation pipeline.
