Page 10: Installation
Figure 4.1: MF5900 meter 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) Cautions during installation: i) It is preferable to first install/connect the meter inlet 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. Please refer to the following recommended installation configuration. www.Siargo.com MF5900 User Manual 9 | P a g e ... - Page 11 (ii) If the upstream or downstream pipe size is different from that of the product, the size of the installation line pipe diameter(s) should be larger than the flow channel (pipe) size of the meters to be installed. For some typical situations, please follow the installation recommendation detailed in the following sketches. (c) 2x90‐degree elbow, 3 D (d) Pipe size‐reduction (e) Pipe size expansion (f) Control valve at upstream or downstream Figure 4.3: MF5900 meter installation (iii) During installation, please make sure no foreign materials (such as water, oil, dirt, particles, etc.) entering into the installation pipeline. www.Siargo.com MF5900 User Manual 10 | P a g e ...
- Page 12 Note: because the meter has a large dynamical measurement range, it could be normal if you see the small instant flow rate before you open the valve as there could be some leakage. However, make sure the meter reads null when there is no flow present in the pipeline. h) This will conclude the installation. Cautions a) Don't alter any parts of the product. b) Ensure the electrical connection is properly done per the instructions. c) Make sure no mechanical stresses in the connections. d) The strong electromagnetic interference sources close by or any mechanical shocks at the pipeline may also create malfunctioning of the product. e) Slowly open/close valves to prevent abrupt pulse flow impact. www.Siargo.com MF5900 User Manual 11 | P a g e ...

Before connecting the meter with external DC power or an AC‐DC adapter, make sure the supply voltage is within the range of the specified ones in Section 7. Be cautious that the standard electrical device precautions such as EDS (electrostatic discharge) and DC voltage are observed. Excessive electrostatic discharge may damage the product. The power and data port is a standard M12. The manufacturer‐supplied M12 cable has the screw locking fixture. Lock the cable and make sure it is properly engaging and will not be accidentally got unplugged. Half‐duplex RS485 Modbus is used for digital data communication. Make sure the wires are properly connected and configured at the receiver side. www.Siargo.com MF5900 User Manual 12 | P a g e ... -
