PT400 Manifold. The nitrogen supply for the system is controlled through a regulator which feeds the manifold assembly. The manifold contains the pressure bars and valves which allow pressurization of the pneumatic lines leading to the in tank probes. The manifold is also connected to the systems single pressure transducer for measuring the in-tank pressures. This patented technique is simple, reliable and requires no calibration.
The manifold enclosure is weather tight and is typically installed outdoors. It contains a heater assembly and has proven reliable even in the extreme conditions of the Canadian Artic.
