Levelstate Colour Port Type Direct Water Level Gauges (DWLG) provide a direct reading of the water level and are suitable for medium & high pressure steam/water applications. Levelstate gauges are reliable and maintenance free thereby minimising operating costs for the user.
Colour port type direct water level gauges operate on the principle of the differences in refractive index of different mediums (steam and water) for indication of the water level. The gauge consists of a vertically oriented metal body with a frosted glass to the front and the rear. The front and rear body surfaces are in non-parallel vertical planes. Behind the gauge body are light sources – red and green. When light passes through the port (submerged in water), it gets refracted at an angle of approximately 10 deg. A Green indication is observed in the illuminator viewing panel. A Red indication is observed when there is no water in the port.
Electronic Drum Level Indicators – A range of electronic units designed for monitoring steam and water levels inside a boiler drum or feedwater tank. Features include upto 48 probe channels, single or dual power supplies, alarm and trip relay output.
A range of electronic units designed to replace mechanical float switches. Features include: single or dual power supplies, probe validation, conductivity settings, 1 to 4 independent channels, local display, relay output per channel.
TYPE 300MP ELECTRONIC LEVEL SWITCH
The 300MP electronic level switch is a multi point replacement for 1 to 4 mechanical float level switch.
1,2, 3 or 4 independent probe channels in one electronic enclosure means the installed cost per detection point can be appreciably lower than traditional float level switches. The system incorporates a probe fault circuit that can distinguish whether probes are in a healthy state. The process fault circuit indicates a change in the normal operating state of each probe (e.g. from steam to water). The Probe Insert Assembly is welded into pipework or vessels at the selected detection points. This provides internal shrouding of the probe for defined water conductivities and a robust housing for external protection of the probe. Multiple Probe Pipework Assemblies can be supplied to suit particular applications. The system is a micro-processor based system that uses a handheld programmer for setup and adjustment.
