Noncontact Liquid-Level Transmitters
Use these transmitters to measure the levels of corrosive, dirty, or sticky liquids without coming into contact with them. They’ll continuously send measurements, so you can monitor status and manage components in your system. Mount at the top of your tank. There should be no tank walls, agitators, or other objects in the path of the transmitter.
Radar transmitters use high-frequency electromagnetic waves and are best for liquids that are tricky to measure because they work even if there’s condensation, foam, or other difficult conditions. They also measure the level of liquids with solids and small solids. In addition to the traditional 4-20 mA output, these transmitters can also send measurements to your Android smartphone or tablet using Bluetooth. There’s an app you can use to set up your transmitter and calibrate it for your system.
IP68 rated transmitters seal out dust and water from temporary submersion.
