I wish I knew what a coplanar pressure transmitter is!
Very good question! When you scale out a new pressure device, you have several types of process connection. Here, coplanar pressure transmitter technology may come up.
In general, pressure devices can measure pressure, level, and flow. But when you decide to measure level and flow, then you need to couple the device to another element, such as a pitot, orifice plate, or a wet or dry leg.
You can find three ways to connect the device to the element: in-line, coplanar, and biplanar mounts. All these options have pros and cons, of course, so you need to decide which provides the most benefits to your process.
A coplanar pressure transmitter mount has two process connections on the bottom of the transmitter, and you usually use it for differential pressure devices. But it can measure absolute and gauge pressure, and it’s fairly light too.
Last but not least, the biplanar mount, our traditional option. It installs on the side of a transmitter for differential, gauge, or absolute pressure. Usually, this connection weighs more than the others and has a more difficult installation.
Companies using coplanar pressure transmitter tech will usually tout its reduced weight, direct mounting, and other advantages. But it’s up to you whether you want to try this style.
