Features:  ½” - 4” line sizes  No power required  Clearly visible meter  Scaled for process fluids  Easy installation—flanged or screwed  No glands or seals  Robust, simple construction  Pulsation damper on gas meter PLATON METAL TUBE VA FLOWMETER TYPE GMT 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 equilibrium 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 1500 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 t o 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, o r 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 \`”-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 totalization is also available, using the “VAMPIRE” electronic module. Metal tube meters are ideal for arduous industrial service as an alternative to large glass tube flowmeters. They have partic- ular advantages, where fluids are opaque or staining, or to provide higher safety and security for dangerous or toxic fluids. PRINCIPLE OF OPERATION The metering element consists of a precision machined tapered tube and a float. The height to which the float rises in taper is determined by the gap at which upward flow force and float weight are balanced. A permanent magnet encapsulated within the stainless steel float drives the external magnetically coupled pointer. Float movement is related to flow rate, and the indicator scale is marked in the correct units of flow for the process conditions. The standard unit requires no electrical power. Because the measuring element is a sharp edged disc, the meter is relatively insensitive to viscosity changes in the fluid, and to pipe bends in the external pipework. The only moving part in the flow i s the float, which is retained in place by float guides at either end of the meter.

Platon Metal Tube VA Gas or Liquid DS1220 ALTERNATIVE FLUIDS Approximate flow ranges for alternative process fluids and gas pressures can be calculated using the following formulae. For a full calculation please contact our Sales Team. 1. Gases at pressure or temperature For air or gas flows where the pressure in the line on the discharge side of the flowmeter is not atmospheric (1.013 bar), multiply the flow range at ATP quoted in the table by a factor calculated as the square root of the pressure (in bar abs) divided by 1.013. Air flow in process = P (abs) 1.013 x Air flow in table For temperature changes: Air flow at T = 293 T (K) x Air flow in table 2. Alternative gases For gases other than air, find the Relative Density (RD) of the gas compared to air, and divide the flow range quoted for air in the table by the square root of the Relative Density. Gas flow range = Air flow in table x Examples of RD figures for some gases are as follows RD Acetylene 0.898 Carbon Dioxide 1.520 Nitrogen 0.968 Argon 1.380 Hydrogen 0.070 Oxygen 1.105 Butane 2.007 Natural Glass 0.608 Propane 1.522 3. Alternative liquids For non-vicious liquids other than water, the main correction arises from the density/SG. For the process liquid flow range, multiply the water flow range from the table by a factor D from below. SG 0.6 For liquid of 1.2 SG, the GMT411L flowmeter would have a full scale flow of 25 x 0.9 i.e 22m³/hr: the scale would be drawn 2-23 typically. Actual scale used would be rounded up, for example 2-23 in this case.

All AVA meters are designed for vertical installations, with flow upwards. It is necessary to have 5 straight pipe diameters upstream and 2 straight pipe diameters downstream. Bends in two places should be avoided. 2. The upstream and downstream pipe bores should suit the normal size of the instrument, if possible. 3. Ensure that no ferromagnetic material is situated within 100mm of the indicator. 4. Before installing the meter, the pipeline should be flushed to remove any foreign matter, or swarf, likely to collect on the float unit and magnet. 5. For ultimate protection a filter should be fitted upstream of the meter to remove large particles.
