Platon GMTX series
Platon GMT metal tube flowmeters are magnetically coupled VA meters for liquids. 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.
Within the tapered flow tube, fluid flow lifts the metering element, which contains a magnet.
More details:
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 GMTX “Vampire” is an electronic version of the standard GMT metal tube flowmeter, where the mechanical pointer and scale is replaced with an LCD to give local meter and digital display of flow rate and flow total. The totally solid state indicator is either loop powered, or mains AC powered with a 4 to 20mA output. High and low alarms are shown on the liquid crystal display panel, and can be signalled to the plant control system. For other liquids, 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.
