Platon GMT series

Platon GMT series

Platon GMT metal tube flowmeters are magnetically coupled VA meters for gasses. Requiring no external power they are robustly constructed for heavy duty, with flanged connections on ½" to 4" line sizes, and screwed BSP connections on ½", 1" & 2" units.

 

More details:

Within the tapered flow tube, fluid flow lifts the metering element, which contains a magnet. The external pointer follows the magnetic field and indicates flow against a clear 150th scale. Standard units are calibrated for air or water, but scales can be produced to suit other fluids and process conditions.

The GMTA and GMTAA are Dual and Dual channel alarmed versions of the standard GMT, fitted with easily adjusted setpoints and indicators. Alarm transmission is provided by NAMUR type proximity sensors, which are approved for use in hazardous areas. Interface modules are available to provide relay outputs, and galvanic isolation for intrinsically safe applications.

For other gases, and for flow measurement at different temperatures and pressures, call Sales who will arrange a custom scale to your requirements. You will need to quote your fluid type, SG, viscosity, pressure, temperature and the units preferred.

*Gas ranges marked with an asterisk are Low Pressure Drop units, designed for applications such as Digester and Biological gas flows, or anywhere where pressure drop is critical.
