TYPICAL APPLICATION

img11

Used to continuously monitor (sense) and indicate level, depth or volume of liquids, slurries or solids in tanks. The basic difference between models is the tank height.

The sensing is non-contact

Transducer is mounted above the highest level in tank and thus will not touch the material. The monitor transmits an ultrasonic signal directed toward the monitored surface and measures the time to receive the reflected echo. The time is then converted to depth or level of liquid in tank. This enables an accurate measurement over the entire range.

The sensors are heavy duty

Designed for durability in harsh industrial environments. Installed properly, they will operate trouble free for a long time, requiring no maintenance. Breakdowns are minimized by a conservative design and many years of field-proven test experience. The sensors are immune to acoustic and electrical noise and turbulence. They are not affected by radio, radar or microwave transmission.To assure a trouble free operation, the circuit has several frequency filters, signal integrator, missing ultrasonic pulse detector, automatic gain control, temperature compensation, signal averaging and output damping for a steady indication. On-board RED indicating light allows checking the operation at glance, blinking light announces every valid echo received.

The transducers are industrial grade

Hermetically sealed, non-corrosive in a PVC housing (std.), 316 stainless steel, Teflon or Kynar. All are intrinsically safe with one model in 316 stainless steel housing approved for Class I, Groups A, B, C & D hazardous environments. The transducer is connected to the controller via a coaxial cable and can be remotely mounted up to several hundred feet, depending on model. Please, see the Transducer page for detailed information.
