Level Gauge Specification


Reliable and accurate determination of levels for Liquid Nitrogen Cylinders.


	Proven reliable and durable unit High impact resistant polycarbonate housing and stainless steel probe Simple push - button operation when used as a 'stand alone' in a vessel Easy plug-in connection point for remote alarm or remote level display Continuous read-out at the storage vessel when connected to the FQLA240 remote alarm or the FQRD240 remote display units Remote units allow monitoring at up to 100 metres in addition to continuous indication at the storage vessel Probe easily fitted into pressure vessels and has been tested up to 1000 p.s.i.



	The Planer FQCG240 Liquid Level Gauge consists of a lightweight, compact electronic gauge head permanently attached to a stainless steel probe of length suited to the depth of liquid to be measured. The gauge head also contains a socket which allows remote units to be plugged into the side and positioned at up to 100 metres away from the monitored vessel. Two different remote units are available. The FQLA240 Remote Alarm Unit, provides an audible alarm should liquid levels fall below a critical point in the vessel. The FQRD 240 provides a display of the level of the vessel via a meter on the front of the unit. The probe, which is inserted vertically, has a capacitance which increases linearly with the depth to which it is immersed in liquid. The gauge head has a meter on the front which provides a direct reading from the vessel.



	A 'vessel fitting' can be supplied to enable the FQCG240 Level Gauge to be installed into a pressured vessel and each gauge is supplied custom made to suit the depth of the vessel being monitored. The FQCG240 is powered either by its own battery when used in isolation or by a low voltage source generated from the remote unit with either the FQRD240 or the FQLA240.



	The probe is inserted vertically into the vessel and an easy to read analogue meter, mounted on the front face of the level gauge head, displays directly, at the push of a button, the height of liquid in the vessel. The gauge is adjusted so that the metre reads 0% when the vessel is empty and 100% when the vessel is full. Alternatively, if a remote unit is plugged in, the meter displays a continuous read out of the current liquid levels (push button not required)
