Liquid Calibration

Our flow switches and flow sensors that are calibrated for liquids are some of the most accurate in the industry, on top of the accuracy we do everything we can to keep our costs as low as possible while using the highest quality materials. Most of our liquid calibrated flow switches are primarily composed of metals such as brass, bronze, SST, and sometimes monel, however we have done some custom units that are made of plastics such as PVC, polysulfone, and polypropylene; if you would like a flow switch made in any material, please reach out to us and if we don't stock it, we can custom make it for you!

Using a flow sensor on lines that are flowing liquids is a reliable way to make sure that you have the correct amount of flow, flowing through your line. They can be calibrated in any orientation, with just about every flow rate imaginable; whether it be on increasing flow, decreasing flow, high pressure, low pressure, etc.; we're confident we will be able to make a unit that suits your needs!

Take a look through the catalog below to see if there is a standard unit that might work for you, you can also choose specifcations on the left to really narrow down your list, alternatively if you would rather us do the work, or can't find a unit that will work, visit our contacts page, or chat with us as we have qualified sales reps waiting to help!
