DESCRIPTION

The INVALCO Model 2100 Net Oil Computer is used to determine net oil, net water, BS&W content, and net gas produced in a well test or similar operation.

Specifications

Enclosure	NEMA 4X fiberglass with clear hinged door. Inner metal door allows easy access to wiring terminals and supports user interface.
Memory	Battery backed RAM memory storage of setup and data values for 10 years.
Power	110-220 VAC 50-60 Hz fused at 2 ampre 12 or 24 VDC fuse type Littlefuse @273002
Inputs Counts Temperature Analog Discrete	3 - dry contact (16Hz maximum frequency) 3 - Pre-amp or photo pulser (10KHz maximum frequency) 3 - pickup coil (10KHz maximum frequency) (Any combination of the count inputs can be configured = 3 meter inputs total) Count Accuracy +/-0.25% of input counts per unit volume. 2 - dual thermistor probe inputs standard (LEMC #5507 probes) -20°F to 150°F standard +/-0.15°F Accuracy 1 - probe for emulsion stream temperature 1 - probe for gas stream temperature averaging. Optional higher temperature ranges available (32°F - 212°F or 60°F - 240°F) 1 - BS&W input scalable for 0-5 VDC, 1-5 VDC 1 - BS&W input scalable 4-20mA (0-100%) 1 - Gas pressure input 1-5 VDC or 4-20mA 3 - Self powered dry contact closure inputs for external monitoring using Modbus Communication. 1 - Self powered dry contact closure input used as system reset integral with reset switch
Outputs	4 - relay NO or NC contacts 10 amp SPDT 3 - relays used for volume pulse output (Net or Gross-tenths of a barrel or cubic foot) 1 - relay for Alarm or Error indication/control 12 or 24 VDC output Serial Communication RS 232 three wire, or RS485 five wire (Modbus RTU communication protocol)
User Interface	Screen - 4 line by 20 character vacuum Florissant display. 4 - touch switches used to scroll through screens and change values 1 - toggle switch for reset
Buttons	FWD - (forward) - moves through displays in a forward direction. REV - (reverse) - moves through displays in a reverse direction UP - increases values on screens where user interface is required DWN - (down) - decreases values or changes current option on screens where user interface is required. Reset - resets totals. Optional external reset with dry contact using terminal block input where Reset switch is terminated also.
