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.
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, 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 of the personnel.
There are no preferred space directions for the installation. 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.
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) Before installation of the product, please ensure that the pipe debris or particles or any other
foreign materials are completed removed.
c) Close the upstream valve, if any, completely.
d) During installation, please make sure no foreign materials (such as water, oil, dirt, particles, etc.)
entering into the installation pipeline.
e) Connect electrical wires per the wire definition in Table 3.1. Please be sure of the power supply
range (i.e., 8 ~ 24 VDC) and power supply polarization. If an adapter is used, make sure the
adapter meets industrial standards and has all safety certifications. Alternatively, this product
can also be powered by a 9Vdc battery.
f) For the data communication wire connection, please follow the description in Table 3.1 and make
sure that the wires are correctly connected to the proper ports on your data device/equipment.
Please make sure the data cable meets industrial standards with proper shielding.
g) Once the external power is successfully connected, for the MF serial of meters, the LED should
be lighted up with the proper information displayed.
h) Slowly open the valve(s) of the gas supply if any, upstream or downstream, or both of the
pipeline. the product should then start to measure the flow in the pipeline. Note: because the
meter has a large dynamical measurement range, it could be normal if you see the small instant
