4. Battery installation For the battery power options, please refer to the following graph to install a battery (C‐Cell lithium battery with 3.6Vdc and 9 Ah). The battery should have the necessary safety certificate. Following the steps to install the battery: (a) Removal of the screws with a screwdriver, 4 screws as indicated by the red arrows: T2 (M2.5) Figure 4.1: Removal of screws (b) Install the battery – for most of the applications, the battery life should be 3+ years. And re‐ assemble the back cover of the meter head. Figure 4.2: Install the battery www.Siargo.com MF5100V User Manual 10 | P a g e ...
Please make sure the data cable meets industrial standards with proper shielding. f) Once the external power is successfully connected or the battery is installed, the LCD should be lighted up with the proper information displayed works correctly. g) Slowly open the valve(s) if any, upstream or downstream or both of the pipeline, followed by slowly open the manual control valve on the meter. And the meter 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 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. www.Siargo.com MF5100V User Manual 11 | P a g e ...

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 MF5100V User Manual 12 | P a g e ...
EDS (electrostatic discharge) and DC voltage are observed. Excessive electrostatic discharge may damage the product. Use the power switch to switch off the power when it is operating with the battery and it will be idle for a longer period for the ultimate optimizing the battery power. Otherwise, although the meter is configured with low power operation, at idle status, the meter will attempt to detect the flowrate from time to time to ensure all data can be properly registered. www.Siargo.com MF5100V User Manual 13 | P a g e ...
The manufacturer‐supplied power and data cable have a 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 at the receiver side. 6.4 Control the flowrate with the manual valve The manual control of the precise flow rate is via the mechanical valve with a 16 turn high precise from fully close to fully open, as long as it is within the specified pressure. Turn the valve slowly for the desired control values. Be careful with the particle contamination that may jam the valve passage leading to control failures. 6.5 Starting the measurement Once the power is supplied (either via battery or external DC power) and no abnormal issues are observed, the meter is ready to perform the measurements. The default display is for the mass flow measurement having two numerical lines on the LCD. The middle line is the totalizer or accumulated flow rate, and the lower line is the instant flow rate. The upper line shows the temperature, meter address, and battery status. www.Siargo.com MF5100V User Manual 14 | P a g e ...
