Solids monitoring saves on maintenance
Alcan has made significant improvements to its bauxite extraction process, through use of the MSM400 sludge density monitor from Solartron Mobrey.
As a result customers can now use this proven, reliable technology to measure the flow of gases and liquids in a wide range of hazardous applications.
The robust metal tube design of the Rotameter 250 is ideal for use in corrosive and aggressive environments such as those found in oil refineries, chemical processing plants and nuclear energy plants.
The new ATEX EExd-approved unit provides reliable indication of flow, within 2% of full scale reading, in high temperature, high pressure applications up to 150C/50bar.
The "blind" 4-20mA output can be used to connect to a stand-alone indicator, PLC or other plant monitoring system.
Within a separate indicator housing, local indication via a large scale and pointer, can be provided, plus if required, two field adjustable alarms.
Designed for easy installation, the new explosion-proof transmitter unit measures just 250mm between flanges as standard, although threaded versions are available.
When installed, the flow meter is mounted in a vertical line with the flow in the upward direction.
When the flow passes through the meter the float rises to a position of equilibrium where the weight of the float is balanced by the net force of the fluid pressure.
The float is magnetically coupled to the instrument, and its movement generates the output signal.
