MODEL 202 RATE TOTALISER
The Model 202
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
Preset to your requirements
Displays rate, total &
Optional 4-20mA output
Optional high & low alarms

Mounts on the pipe, wall or
Battery or DC powered
The 202 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 liqiud when used with
turbine, positive displacement and pelton wheel flowmeters. The battery powered
version is ideal for areas where a power supply is not
and the resettable total are displayed simultaneously. The 202 stores a non
resettable total to monitor long term consumption .
Installation and Setup
The rate and totals can be displayed in any engineering
units for example litres per minute and barrels. The setup is easy via the
front keypad and it can be preset for your requirements.
The 202 can be
mounted directly on to your flowmeter, wall mounted or pipe mounted. Cables are
installed via waterproof cable glands.
Analogue 4-2OmA output
An optional two wire 4-2OmA output is available
for transmitting the flow rate to other instruments or control equipment. It is
scalable 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. High and low flow alarms
Two flow rate alarms are available for monitoring the flow. The output will
trigger when the flow rises above or falls below the high and low alarm levels.
This option requires a DC power supply. 3.
Linearisation: The accuracy of your system can be improved by programming
any flowmeter errors into the 202.
