  • Gapmeter Type SGUV Platon DS1160

    Gapmeter Type SGUV | Platon DS1160

    Gapmeter Type SGUV - Overview

    The type SGUV and type SGUL are direct reading Flowmeters for clean liquids and gases in pipe sizes larger than 30mm. They provide a robust and cost effective method of flow measurement. The indicator housing can be mounted locally to the pipe or remotely by the use of flexible impulse tubing. The instrument is a combination of two measuring principles. It is essentially a pressure differential device consisting primarily of an accurately machined orifice plate located in the main pipework. This produces a pressure drop proportional to the square of the flow rate. A secondary orifice restrictor located in the by-pass flowmeter is accurately calibrated to produce a by-pass flow that can be measured by the glass VA type flowmeter, scaled in terms of the main pipe flow. The metering elements are manufactured to a high standard of interchangeability with boldly marked indicating scales and dynamically balanced floats.
