EASY TO READ
Features 6 digits of bright red 7-segment LED displays that are .55 inches high.
TWO PROGRAMMABLE RELAYS
The standard 10 Amp form C relays allow precise flow rate and batch control.
DUAL POWER OPERATION
Units are designed to operate on 110 VAC or 12-24 VDC.
USER SELECTABLE ANALOG INPUT
The R100 and R/T100 permit standard analog inputs of 0-5V, 0-10V, 1-5V, 4-20mA and 0-20mA.
RATE FUNCTION: R100 AND R/T100
Displays 4.5 digits of user scalable flow rate information.
TOTALIZER FUNCTION: R/T100
Accumulates up to 6 digits of information. The totalizer divider allows total division by 1, 10, 100 or 1000.
Engineering Specification
THE DIGITAL TOTALIZER/RATE METER SHALL:
- Interface directly with Lake Monitors' flow rate transmitters.
- Provide 4.5 digits of rate information and 6 digits of totalized information.
- Have two programmable 10A relays.
- Have user scalable units of measure.
- Have a NEMA 4/IP 65 front panel.
- Have EEPROM memory backup.
- Require a 1/8 DIN panel cutout.
- Be Lake Monitors Number R100 for rate only measurements or R/T100 for rate and totalized measurements.
