Trimec rt11 - Overview; LCD Displays

4 Introduction
1.3 Overview
The RT series instruments are specifically designed for computing, displaying and
transmitting totals and flowrate from flowmeters with pulse or frequency outputs.
The instrument will display Flow Rate, Resettable Total and an Accumulated Total in
engineering units as programmed by the user. Simple flow chart programming with scrolling
English prompts guide you through the programming routine greatly reducing the need to
refer to the instruction manual. All user program data is retained if the battery is removed.
Special Features
Standard
: 10 point Linearisation, PIN Protection, NPN/PNP selectable autoranging pulse
outputs (scaled or un-scaled), Low frequency cut-off, Battery conservation mode.
Optional : 4~20mA output, High / Low flow alarms with adjustable deadbands, Dual inputs.
Environments
The RT is weatherproof to IP66 (Nema 4X) standards, UV resistant glass reinforced nylon
with stainless screws & viton O-ring seals.The instrument suits harsh indoor and outdoor
environments & conforms to EMC directive 89/336/EEC Electro Magnetic Compatibility.
Conforming standards include: EN 61326 ( immunity in industrial locations )
EN 62326 ( emissions in industrial locations )
EN 60529 ( degrees of protection [ IP ] )
Installation
Specifically engineered to be directly mounted on a variety of flowmeters, wall or surface
mounted, pipe or panel mounted. Various mounting kits are available. The instrument can be
self powered or may be powered by an external dc supply or two wire loop powered.
