PLATON Metal Tube Flowmeters
May the flow be with you...

PLATON Metal Tube GMTE Flanged or Screwed VA Flow meter – NEW!
GMT & GMTE metal tube flowmeters are variable area meters of totally welded stainless steel construction. Liquid or
Gas flowing up the tapered flow tube 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 160° 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 flow tube’s robust construction with no glands or seals to leak, means the meters are suitable for high pressure
applications, or extremes of temperature. While the GMT is totally self-contained and needs no external power, the
GMTE combines a mechanical meter with an electronic 3-wire transmitter. The GMTE features, adjustable low and high
alarm with LED indicator, totalisation, 4-20 mA output, adjustable averaging of the flowrate reading, heartbeat indicator,
and backlit LCD display.

- ½” - 4” line sizes
- Mechanical flowmeter
- Electronic flowmeter
- Clearly visible meter
- Scaled for process fluids
- Easy installation—flanged or screwed
- Robust, simple construction
- Pulsation damper on gas meter

PLATON Metal Tube GMT Flanged VA Flow meter
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 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.

PLATON Metal Tube GMT Screwed VA Flow meter
Part of the Platon GMT Variable Area flowmeter family, models GMTB and GMTS are brass or Stainless Steel tube flowmeters with female screwed connections. With 1/2”,1”and 2” BSP/NPT threaded fittings standard, the meters are ideal for arduous industrial service as an alternative to large glass tube flowmeters. They have particular advantages for gas or liquid flow measurement at high pressures and temperatures, where the fluids are opaque or dark colored or to provide higher operational security for dangerous or toxic materials.

- Economic construction
- BSP/NPT Screwed end fitting
- Brass or Stainless Steel
- Wide flow ranges
- Sizes 15, 25, 50mm. 1/2”, 1”, 2” bore
- Integral damping on gas flow lines
- Local indication
- Calibration for wide range of gases and liquids

PLATON SC250 Metal Tube Flowmeter
Flowmeters are based in the variable area principle. The metering system consists on a calibrated orifice and a conical float. The force from the fluid, as it flows from the bottom to the top, displaces the float until it reaches an equilibrium point. Each float position represents an area between the float and the orifice.
This area corresponds to a flow rate.

- Metallic tube with a robust construction
- Indication by means of magnetic coupling
- High performance measurement in extreme working conditions and highresistance to corrosion
- Low pressure drop
- Damping mechanism to avoid float bounces in gas and steam applications
