Source water bar screens

Source water & bar screens

As the largest industrial user of process water, pulp and paper mills are often located next to natural water sources. Bar screens are placed in intake channels or wet wells to remove debris that could damage mill equipment. When debris has accumulated, screen cleaning is accomplished with an automated rake typically actuated by a level control mounted in an upstream channel.

Challenge

Water levels of intake channels and plant wells require monitoring. Though normally a routine application, freezing weather can cause complications for level controls, especially those that actuate screen cleaning. A level control operating in frigid, outdoor conditions must be accurate and reliable despite icing conditions.

Non-contact radar model R82 pulse burst radar transmitter

Radar has been part of the level measurement market for more than thirty years. The early designs used in tank gauging were heavy, expensive, power-hungry and complex. Advancements in radar circuitry have evolved the modern radar transmitter so that now it is light, inexpensive, loop-powered and easy to use. The R82 is the logical extension of that evolution.

Microwave-based radar is a superior measurement technology with its ability to operate effectively in a wide range of process conditions. It has been too expensive to use as a replacement for ultrasonic transmitters in simple, daily applications...until now. The R82 radar transmitter can be considered the answer to almost every daily level measurement application imaginable.
