INVENTRON

INVENTRON has been the leading manufacturer of ultrasonic transducers since the 1960's. A section of this catalog describes ultrasonic sensor input devices.

THE CONVERTIBLE™ by INVENTRON combines advanced micro-processor circuitry. It can function in either a tank level or flow mode providing TANK level and volume as well as flow for all types of open channel devices. All calibration information is stored in non-volatile memory so that lose of power does not affect field calibration data.

THE CONVERTIBLE(tm) can be configured with different sensor inputs. The unit has been designed to accept the following inputs:

ULTRASONIC
           MAGNETORESTRICTIVE
                     ANALOG (voltage or current)
                               CAPACITANCE
                                         FREQUENCY

These capabilities allow the user to standardize on a single intelligent control interface. This feature can minimize operator training, resulting in increased productivity since one user interface serves many types of control equipment. Pressure transducers, as well as capacitance sensors, which provide a 4-20 MA output signal are available from a wide variety of manufactures. Any device which provides a flow- proportional signal can utilize the scaling, totalization, and digital output of THE CONVERTIBLE™. Specific applications utilizing these input devices are covered in application bulletins.

Programming Security - To activate the programming mode, the user enters a personal identification code (similar to PIN codes commonly used on banking terminals). Unless the unit is so activated, existing data can be read, but no new data can be entered.

Portable Keypad Enclosure - The keypad is available in a portable enclosure. This may be used with blind transmitters where either a digital or analog signal is sent to a remote receiver. In this case. one keypad could service multiple unmanned pumping stations, and similar situations where the use of the keypad is mainly limited to initial setup.

General - The keyboard contains 20 keys for data entry and programming. Various functions such as the setting of the alarm/control relays are menu driven for ease of data entry, providing a user-friendly interface. The 48 character Liquid variables at the same time. Also, as functions are entered, the unit utilizes the capabilities of the LCD to provide the names of the functions and to prompt the data entry.

The units on the display can be field programmed so that any variable can be chosen such as feet, inches, centimeters, gallons, pounds, kilograms.
