1. Overview
MF5600 mass flow meters are designed for general purpose precise industrial gas measurement,
monitor or control. The design opts for applications where the display must be separately placed from
the meter body or flow channel.
The meters are operated with the Siargo’s proprietary MEMS thermal mass flow sensors together with
the smart control electronics. The sensor probe surface is passivated with silicon nitride ceramic
materials together with a water/oil proof nano-coating for performance and reliability. The current
models are ready to connect to 12mm or 19mm lines while other pipe diameters can be offered as
customized models. The meter body is made of stainless steel that is available for applications of most
of the gases.

MF5600 Series MEMS Mass Flow Meters feature:
Integrated MEMS mass flow sensors
Large turn-down ratio over 30:1
Excellent repeatability and accuracy
Low pressure loss
Various user interface for plug-and-play and remote communication or network
Detachable LCD display for offsite data processing
The MEMS calorimetric sensor is installed at the flow channel wall forming a plate that serves as an
additional flow conditioner from the boundary layer configuration resulting in a laminar flow. The mass
flow measurement is established as the fluid carries heat away from the heater causing the redistribution of
the temperature field. Accurate flow rate is obtained by calibration with the standard fluid at the preset
conditions.

5.2 Installation Instructions
The product at the time of shipment is fully inspected for product quality and meets all safety
requirements. Additional safety measures during the installation should be applied. This includes,
but is not limited to leakage verification procedures, standard EDS (electrostatic discharge)
precautions, DC voltage precautions, and heavy duty precautions. Other tasks such as calibration,
part replacement, repair, and maintenance must only be performed by trained personnel. Upon
requests, manufacturer will provide necessary technical support and/or training of the personnel.
Do not open the product cover or alter any part of the product. Any such actions will forfeit the terms
of the warranty and cause the liability to any damages thereafter.
The product is preferably to be installed horizontally. Flow direction should be aligned with the
arrow mark on the meter body. If the flow 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 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) Cautions during installation:
(i) It is preferably to first install the inlet end of the meter and then the outlet end of the meter; To
ensure the measurement accuracy, an upstream straight pipe of length no less than 10DN and a
downstream straight pipe of length no less than 5DN should be in place.
(ii)During installation, please make sure no any foreign materials (such as water, oil, dirty,
particles, etc.) falling into the pipe.
d) Connect electrical wires for LCD, and then electrical wires for inputs/outputs. Please pay special
attention to power supply range (i.e., +12~+24 VDC) and power supply polarization (see the
description on Electrical Interfaces in this manual).
e) When connect the communication wires, please make sure that the wires are correctly connected
to the proper ports on your data device/equipment.
f) Turn on the power supply, and make sure that the LCD works correctly.
g) Slowly open the valves at the both ends of the pipeline, and the meter should then start to measure
the flow in the pipeline
h) Completion of the installation.
5.3 Cautions
a) Don't try to loose any build-in part of the product.
b) Ensure electrical wires for the inputs/outputs to be reliably connected.
c) Release all the installation stresses so that no stresses will be exerted on the product.
d) The product should avoid strong electromagnetic interference sources nearby or periodic
mechanical shocks to its body or pipeline.
e) Slowly open/close valves to prevent abrupt pulse flow impact, which may damage the product.
