The
SERIES RTI2
Rate & Total Indicator is an indicator/transmitter that takes the pulse
output signal from compatible flowmeters, displays flow rate and total, and provides
output signals. It is compatible with the Series EFS2, IEFS, PDWS, and FLMG.
FEATURES/BENEFITS
• Can be mounted on a wall or mounted on the flowmeter for added flexibility
• Accessory mounting kits make it easy to change the mounting orientation
• High environmental protection with semi-flexible urethane potted electrical
components
• Provides a pulse, 4 to 20 mA and dual-relay output
APPLICATIONS
• Water treatment
• Water utilities
• Industrial chemical handling
The
SERIES BAT
Analog Transmitters is a 4 to 20 mA transmitter for use with the
Series EFS2, IEFS, PDWS, PFT and FLMG.
FEATURES/BENEFITS
• Easy to set up and can be either wall or meter mounted
• Takes a pulse frequency output from the compatible flow meters and converts it into
a continuous 4 to 20 mA analog output signal
• The frequency for the flowmeter output signal can be adjusted using four rotary
switches on the back of the transmitter and a microcontroller automatically scales all
other values accordingly
• The microcontroller averages inputs for more stable reading outputs and is adjustable
from 2 to 16 seconds
• Loop powered, 2 wire connection
• High environmental protection with semi-flexible urethane potted electrical
components
APPLICATIONS
• Telemetry applications
• Distributed control systems
• Data logging
• Chart recording
