Economical Ratemeter, Totalizer & Batch Controller

The SUPERtrol 1LE (ST1LE) batch controller is a flow batcher for use with pulse producing flowmeter types in liquid applications.
The alphanumeric display shows flow rate and flow total as well as measured and calculated parameters in easy to understand format. Single key direct access to measurements and display scrolling is supported. An EZ Setup feature rapidly guides the user through the basic setup.
The SUPERtrol-I LE can be programmed for rate/total indication or batching. The various pulse inputs and outputs can be “soft” assigned to meet a variety of common application needs. The user “soft selects” the usage of each feature while configuring the instrument.
A 0-20mA or 4-20mA analog output is standard. The user can assign the standard RS-232 Serial Port for data logging, transaction printing, or for connection to a modem for remote meter reading.
An optional RS-485 serial port using Modbus RTU protocol is available. A Service or Test mode is provided to assist the user during start-up system check out by monitoring inputs and exercising outputs. The system setup can also be printed.

For Pulse Inputs the Count K-Factor is equal to the number of pulses per unit of measure which is determined by the flowmeter. (This Information is typically on the flowmeter calibration sheet or stamped on the flowmeter itself).

The Rate Time is menu selectable it can be found in the “Setup Indicators Menu” under “Rate”. You will have the option of choosing Seconds, Minutes, Hours or Day which adds the appropriate multiplier into the equation.

The 4-20mA current span is the span you expect the Supertrol-1 to interpolate between. The Supertrol-1 is scaled by assigning a “Low Range” and a “High Range” to the analog Low and High inputs of the Flow Input Menu. Let’s say that the sensor has an output of 4mA (milliamps) when it measures “0” GPM and 20mA when it measures “10” GPM. Through the keyboard you enter in “0” for 4mA (Rate Low), and “10” for 20mA (Rate High) and you have completed scaling the unit. Typically the customer will tell you the range they would like to use for their application.

The unit is shipped from the Factory with an Operator Password of “0” and a Supervisor Password of “2000” these should be tried first before giving the customer the back door code. The Factory back door code can be obtained by calling the factory or send an email.

Yes. The analog output is Isolated. Below you will find the specifications for the analog output that customers usually ask about.

The Analog Output is: Isolated Current Sourcing, Isolated I/P/C: 500 V
The Available Ranges are: 4-20 mA, 0-20 mA
The Resolution is: 12 bit
The Accuracy is : 0.05% FS at 20 Degrees C
The Update Rate is: 1 update/sec minimum
The Temperature Drift is: Less than 200 ppm/C The Maximum Load is: 1000 ohms (at nominal line voltage)

Yes. The Supertrol-1 is equipped with a battery backed real time clock that displays time and date. The format is: 12 or 24 hour time display and Day, Month, Year date display.

Yes, the front panel is NEMA 4X rated. This rating is also comparable to the European standard IP65.

The user can view the Rate and Total of flow as well as the Grand Total, Temperature, Density, Time, Date, Preset 1 and Preset 2. This can be accomplished by pushing the appropriate button on the front of the unit or by setting up the Scroll List to display the the information desired through a scrolling display

The Supertrol-1 has the following Listings: “CE” which is the European noise immunity Standard, and  which is the Underwriters Laboratories of Canada Standard.

The D.C. output is rated at 100ma maximum current draw. The D.C. output is also selectable. The user can select from three excitation voltages of 5, 12 or 24 Vdc to power their transmitters

Below you will find typical wiring diagrams to help you wire a flowmeter to the Supertrol-1
