1. Introduction 1.1 Product Overview The RT14 Rate Totaliser is designed for computing, displaying and transmitting totals and flowrates 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 scrolling English prompts guides you through the programming routine greatly reducing the need to refer to the instruction manual.

2.3 Operating Functions Resettable Total 2.3.1 The display toggles between Rate and Total displays when the RATE/TOTAL key is pressed. Pressing the RESET key and holding for a period of 3 seconds while the Total is displayed on the LCD will cause the Total to reset to zero. 2.3.2 Accumulated Total The Accumulated Total is displayed momentarily whenever the ACC.TOTAL key is pressed, holding the key will hold the Accumulated Total display.

2.3.4 Display Backlight The display backlight will be automatically enabled upon connection of an external DC voltage supply in the range of 12-30V; the backlight is not available when operating on battery or loop power. If it is required to reduce power consumption while operating on external DC power the backlight can be overridden in the Advanced Menu (see section 5.10).

2.3.7 Scaled Pulse Output The Scaled Pulse Output is used to transmit the totalised volume at a user selectable resolution; this is programmed as a volume quantity per output pulse (e.g. 10Litres/Pulse or 100mL/Pulse). The frequency of the Scaled Pulse Output signal automatically adjusts according to the input frequency and the scale factor, up to a maximum limit of 100Hz.

5 years of battery life; average conditions are considered to be a reed switch input from a Flomec flowmeter with no outputs used. High input frequencies (~1kHz and higher) from a turbine flowmeter will reduce battery life by around 20%, and operation of a battery powered scaled pulse output will reduce battery life by approximately 50%.
Page 12
The instrument is equipped with a regulated sensor supply (5V/20mA maximum) terminal which is suitable for powering hall-effect sensors in Flomec flowmeters. The sensor supply is only available when the instrument is connected to an external 12-30V DC supply, it is not available under loop power.
Page 13
This instrument may be purchased as a meter mount display which will mount on the top of any Flomec flow meter. For any instruments purchased as field mount, these may be converted to a meter mount instrument by purchasing a new rear enclosure.
Page 14
3.5 Panel Mounting Mounting of the instrument in a panel requires a 106mm (±2mm) / 4.10” - 4.25” round hole to be cut in the panel – maximum panel thickness 6mm (1/4”). The Panel Mount Seal Kit (part no. 1504003) must be used to maintain weather protection when panel mounted. IP65 is possible with the seal kit used.

4. Electrical Installation All wiring connections should be made with good quality shielded instrument cable; wiring between terminals which are inside the instrument enclosure, or between a flowmeter and an integrally mounted instrument may use non-shielded wire. Cable shields or drain wires should be connected to the instrument ground (GND) at the instrument end only –...

6. Programming Parameters 6.1 PIN Program Protection Any user defined PIN other than 0000 will engage the program protection mode; after the PIN protection mode is enabled failure to input the correct PIN number will deny the user the ability to change any of the program parameters, but will allow read only access to the user so that they may view existing program settings.

6.4 Decimal Places Decimal places are separately adjustable for Total, Accumulated Total, and Rate from zero to three decimal places. The decimal places setting for Rate will set the available decimal places in the analogue output set point. The decimal place settings for Total and Accumulated Total do not influence configuration of the pulse output.

output the signal at the maximum of 100Hz, and all excess pulses will be stored in memory until such a time that flow has stopped and the instrument can output the stored pulses – it is not recommended that systems be designed to operate in this way under normal conditions. The output frequency can be calculated as follows: ...

6.10 Advanced Menu 6.10.1 Resetting Accumulated Total Resetting the accumulated total can only be done at this level of the Advanced Menu; by PIN protecting the instrument it is possible to remove the ability of an operator to reset the accumulated total.

However it should be kept in mind that for any battery powered applications, using a value lower than the default will decrease battery life. 6.10.5 Analogue Output Adjustment The analogue output may be adjusted/trimmed at this level of the program; this should not be necessary in most applications as the analogue output is factory calibrated, however it may be useful when operating at extreme ambient temperatures.
