1. Introduction
1.1 Product Overview
The RT40 Rate Totaliser is designed for computing and displaying volume and volumetric
flowrate from a flowmeter with a pulse or frequency output. The instrument will display Flow
Rate, Total and Accumulated Total in engineering units as programmed by the user. Simple
flow chart programming with English prompts guides you through the configuration steps,
greatly reducing the need to refer to the instruction manual. Your instrument is also USB
enabled and may be configured on a windows PC using a software utility downloaded from the
FLOMEC website. This instruction manual contains some basic information on using the
FLOMEC software utility, however please refer to the instruction manual provided with the
software for detail instructions on its use.
Environments
The instrument is weatherproof to IP65 standards; a UV resistant glass reinforced nylon
housing with stainless steel screws and Nitrile seals allow the instrument to maintain its
environmental protection across a wide operating temperature range. The instrument suits
harsh indoor and outdoor environments & conforms to the European Directive for Electro
Magnetic Compatibility.
Features
Displays of total, accumulated total, instantaneous flowrate, and min/max flowrate are
available on the LCD. Flows are computed using 5-point linearisation which allows accuracy
improvements for the connected flowmeter. Computed values can be retransmitted to a
separate control system using the selectable digital output, with scaled pulse, unscaled pulse
or High / Low flow alarms available.
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.
