New Ultrasonic Liquid Level Control System Introduced By Inventron

Inventron Industries Inc. of Klamath Falls, Ore., has introduced a microprocessor-based level control system dedicated to pump control.

The new system, named the LS-99, uses ultrasonic transducers to detect product level in tanks and other vessels.

Among the key features of the LS-99 is an array of front panel controls that permit the user to perform all start-up and calibration routines without opening the controller cabinet. The standard configuration of the LS-99 is designed to handle single and duplex pump stations, but as many as eight pumps can be controlled. The controller for the LS-99 can be purchased without an ultrasonic control card, and thus can be used to control the 4-20 mA signal of essentially any type of level-control device.

Lead and lag pump capability is included, and four thumbwheel switches on the front panel permit easy and fast changes in settings.

Optional high and low alarms can be included if desired. Analog voltage outputs are included, and optional current outputs are available with the system.
