What is a coplanar manifold?
Coplanar manifolds have the process connection coming in from the bottom and don’t require a process flange. They’re available in 2, 3, or 5-valve assemblies, with a 5-valve gas metering pattern also available. You can get coplanar manifolds with ½” or ¼” process connection sizes.
How does a 3 valve manifold work?
A three-valve manifold is a device that is used to ensure that the capsule will not be over-ranged. It also allows isolation of the transmitter from the process loop. It consists of two block valves – high pressure and low pressure block valve – and an equalizing valve.
How do you calibrate a DP transmitter with a manifold?
The procedure for calibrating DP transmitters is first to connect the transmitter manifold to a pressure source. Next connect the transmitter to a configuration tool such as the AMS Trex device communicator and then perform a zero trim function and an upper sensor trim function.
What is a manifold on a valve?
A manifold is a device that connects one or more block/isolate valves of a hydraulic system. Valves of a hydraulic system can include a ball, needle, bleed and vent valves.
What is the use of 5 way manifold?
5-valve manifolds allow for in-place transmitter calibration, provided one of the ∆P transmitter’s sides has an atmospheric vent. By connecting the calibrating pressure source to the vent line, one can route the calibrating pressure to either side of the transmitter (only), while keeping the other side vented.
What is a 3 way manifold?
A three-way manifold valve is a device that is used to ensure that the capsule will not be over-ranged. It also allows isolation of the transmitter from the process loop. It consists of two block valves – high pressure and low pressure block valve – and an equalizing valve.
When would you use a 5-valve manifold?
3-valve manifolds are normally used on differential pressure transmitters where it is necessary to block each process connection or equalize two sensor diaphragms. 5-valve manifolds are also used on differential setups and provide the ability to block, equalize and vent two process connections.
