RT7 RATE TOTALISER    

The RT7 takes the pulsed output from any flowmeter and displays the flow rate and total of your process liquid.

Easy to use and to set up
Large easy to read displays
Preset to your requirements
Improves flowmeter performance
High and low alarms
Monitor your process
Robust design
Splash proof keypad

Application
The RT7 gives you a display of the flow rate and total flow of liquids in your application. You can use it for monitoring, controlling, dispensing, blending or filling of any liquid.

Operation
The RT7 takes a pulse input from your flowmeter and simultaneously displays the flowrate and total. It also displays a non resettable accumulated total at the touch of a button. High and low flow rate alarms can be used as part of a safety system to protect your plant. There is a scaled pulse output and an analogue 4-20mA output for transmission to other instruments or control equipment.

Installation and Setup
The setup is easy using the keypad and a 'beep' is sounded with all keystrokes. The RT7 can be supplied preconfigured for your application.
Operator access to the setup menu can be inhibited. The displays can be set for any units e.g. litres or gallons.

Features

Alarms: Two flow rate alarms are available. The low alarm relay will energise when your flow rate falls below a preset value. The high alarm relay will energise when your flow rate rises above a preset value.
The relays can be used for audible or visual alarms or to safely shutdown systems to protect equipment. The LED’s on the front panel will indicate when there is a high or low alarm condition.
Analogue output:
An optional 4-20mA or 0-10V output is available for transmission to other instruments or control equipment. It is scaleable to your requirements and provides an accurate and fast response to changes in flow rate.
Linearisation: The accuracy of any flowmeter can be improved by programming the calibration errors of the flowmeter into the RT7.
Damping: Decreases the response time to steady the display of the flow rate. The level of damping can be adjusted depending on how erratic the readings are due to liquid turbulence, pump pulsation or fast valve actuation.

Construction
The RT7 has a tough aluminium case in standard ¹/₄ DIN format for mounting in a panel. The front bezel and keypad has a splashproof seal that is resistant to most chemicals.
