RTB
RATE TOTALISER 
The RTB has an
LCD display of flowrate and flow total. It takes the output from flowmeters and
can be used for local or remote indication.
Quick and easy to setup
Preset to your requirements
Displays rate, total & accumulated total
Optional 4-20mA output
Mounts on the pipe, wall or flowmeter
Battery, DC or loop powered
Intrinsically safe version
Waterproof enclosure
Application
The RTB Rate Totaliser is designed to display the flow
rate and total of your process liquid. You can use it for monitoring,
controlling, dispensing, blending or filling of any liquid when used with
turbine and pelton wheel flowmeters. The battery powered version is ideal for
areas where a power supply is not available.
Operation
The flowrate
and a resettable total are available at the press of a button. The RTB stores a
non resettable total to monitor your total consumption.
Installation and Setup
The display can be in any engineering units, for example
litres per minute. Control is easy via the front keypad and it can be preset
for your requirements.
The RTB can be mounted directly on to your
flowmeter, wall mounted or pipe mounted. Cables are installed via waterproof
cable glands.
Optional
Features
1. Analogue 4-2OmA output
An optional
two wire 4-2OmA output is available for transmission to other instruments or
control equipment. It is scaleable to your requirements and provides a fast
response to changes in flowrate. The operating power is drawn from the 4-2OmA
loop so that the batteries will last indefinitely.
2. DC
power supply
This option requires a DC power supply of 8-35V.
Construction
The instrument is housed in a watertight enclosure and
cable entry is via cable glands.
