Platon Screwed Metal Tube VA
Flowmeter
PLATON GMTB & S SERIES

FEATURES

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
coloured or to provide higher operational security for
dangerous or toxic materials.

Calibration for wide range of gases

The VA meter principle used in the Platon GMT
flowmeter measures the position of a float in a
precision-machined tapered tube. The float rises
with the flow up the taper until the upthrust from the
flow balances with the weight of the float. A magnet,
electron beam welded into the float casing, drives
the external meter indication over a 100mm scale
typically displaying a 10:1 flow range.

Optional electronic outputs

Options available on the GMTB/GMTS include
(GMTA) flow alarm outputs for high or low adjustable
set points and electronic 4-20mA flow transmitter
(GMTX) outputs. All of these are available with
CENELEC intrinsically safe approval. For low-pressure
Natural gas flow measurement, models are available
with minimal line pressure loss. Special versions are
available for Oxygen service. All units are available
calibrated for the specific line conditions or fluid
involved.
