Installation requirements for metal tube float flowmeters in various environments. Installation for dirty fluids: A filter should be installed upstream of the instrument. When a metal tube float flow meter with magnetic coupling is used for fluids that may contain magnetic impurities, a magnetic filter should be installed in front of the meter. It is necessary to keep the float and the cone tube clean, especially in instruments with small diameters; the cleanliness of the float has a significant impact on the measurement values. Installation of pulsating flow: If the flow itself is pulsating, for example due to the presence of a reciprocating pump or control valve upstream of the instrument to be installed, or due to large load variations downstream, it is necessary to change the measurement location or take corrective measures in the piping system, such as installing a buffer tank ； If the oscillation is caused by the instrument itself, such as too low gas pressure during measurement, valves upstream of the instrument not being fully open, or the control valve not being installed downstream of the metal tube float flow meter, appropriate measures should be taken to address these issues, or an instrument equipped with a damping device should be used instead. Installation with an expanded range: If the flow rate range required for measurement is wide, with a range exceeding 10, two floats of different shapes and weights can be placed within a single instrument. For low flow rates, the reading is taken using the lighter float; once the float reaches the top, the reading is taken using the heavier float. This allows the range to be expanded to 50–100. To drain the liquid, use the gas inside the instrument: For metal tube float flow meters whose inlets and outlets are not aligned in a straight line, when using them with liquids, it is important to check whether there is any air remaining in the extension tube that transmits the float’s movement; this air must be drained ； If the liquid contains tiny bubbles, they tend to accumulate inside the casing during flow, so it is even more necessary to vent regularly. This is even more important for small-diameter instruments; otherwise, it has a significant impact on the flow reading.
