Variable-area flow meter GMT

volumefor liquidsflange

GMT metal tube flowmeters are variable area meters of totally welded stainless steel construction. Liquid or Gas flowing up the tapered flowtube lifts the float to an equalibrium position, dependent on flow rate, and a magnetically coupled pointer indicates this flow on an external scale. The large meter indication is easily visible at a distance, with the pointer moving over a 150° scale. Each scale is produced specifically for the fluid involved and process conditions expected: several flow ranges are available for meters of each standard line size. All gas flow meters are supplied with an integral piston damper to smooth out flow pulsations. Installation is simple, in a vertical section of flow line: meters can be supplied with EN, ANSI or other standard flanges, or BSP or NPT screwed connections. The robust construction with no glands or seals to leak means the meters are suitable for high pressure applications, or extremes of temperature.The standard GMT is totally self contained and needs no external power. Alternative materials are available to special order - for example Hastelloy or Monel wetted parts. For lower cost, Brass or Stainless steel bodied meters ½ - 2 in size are available with screwed connections.The indicator can be provided with one or two flow alarm sensors, adjustable over the meter operating range. Full electronic transmission and totalisation is also available, using the VAMPIRE electronic module.
