Whether you are looking for a solution to solve a water supply issue to a building or trying
to monitor a process tank within your factory, the proper tank level is extremely important
to the success of your project. There are countless applications across many industries that
with a few simple steps can ensure that you can meet the needs of your project.
What type of tank do you have? There are two main types of tanks that are used in the HVAC
and Industrial markets; vented and sealed tanks. This simple question of the type of tank
will drive the entire decision making process of your application, so the decision is crucial.
A vented tank is any tank, regardless of size or shape, which has a liquid in which atmospheric
pressure (approximately 14.7 psi) is the only force on top of the liquid in that tank.
One of the most recognizable vented tanks is an elevated water tank. An elevated water
tank can be used to supply the proper water pressure to a factory or neighborhood that
may not have adequate pressure to service the application. Other applications include oil
tanks, stand pipes, sewerage wet wells, fire prevention tanks in remote communities and
food and beverage manufacturing.
Measuring the liquid level in a vented tank can be completed in a variety of ways, with
many different levels of accuracy. The first thing you need to know is if your vented tank is
above ground or if your tank is buried in-ground. An above ground tank will typically have
a process connection external near the bottom of the tank as well as a way to access the
tank from above. A tank that sits in-ground will typically have an access hatch that you can
access to install your sensor.
