RT20 Rate Totaliser Displays Flowmeter Data

Trimec-Europe has brought out a flow-rate totaliser designed for computing and displaying flow rates and totals from flowmeters with pulse, sine wave or frequency outputs. The RT20 Rate Totaliser can be battery or externally powered and features a six-digit large LCD total, eight-digit cumulative totaliser and five-digit rate display.

The instrument displays resettable (batch) total, cumulative total and instantaneous flow rate in engineering units as programmed by the user. A robust IP66/67-NEMA 4X aluminium field and panel-mountable housing make the unit suitable for rugged applications. It also features a backlit panel enabling distance viewing at night when de-powered. The RT20 is designed for simple PIN-protected flow-chart programming, with English-language prompts guiding users through the programming routine, which reduces the need to refer to the instruction manual.

Other features include scaleable universal pulse or frequency inputs, scaled pulse output, long battery life, non-volatile memory and reverse-polarity protection. Additional options to suit specific applications include a heavy-duty facia protector shield, a relay board with SPDT outputs and flowmeter and pipe-mount kits. Other units available include battery totalisers, automatic batch controllers and a rate totaliser with 4-20mA, alarm and scaleable outputs, dual-flow inputs and linearisation.

Flowmeter Ideal For Air Leakage Detection

Endress+Hauser has launched the ATT12A thermal air flowmeter, designed for compressed air applications. The ATT12A airflow trend meter is said to be ideal for use in air distribution, compressed air monitoring and air leakage detection.

The meter features an IP66 stainless-steel housing and all-stainless-steel construction. It can be installed in any location. Covering a range of line sizes and flow rates, the ATT12A t-trend can achieve substantial savings by monitoring compressed air usage and leakage, according to Endress+Hauser.

It features a push-button function offering user-friendly menu navigation and device configuration. Its illuminated LED switch point flashes in the event of any programming failure, meaning users are informed of the error immediately. The LCD display allows simple programming of the device through a guided menu and shows the measured values as well as the percentage of maximum flow rate and error codes providing information about the current status.

Flow Technology Unveils FT/DF Turbine Flowmeter

Flow Technology, a manufacturer of precision flow-measurement instruments, systems and calibrators, has introduced the FT/DF (diesel-fuel) turbine flowmeter system. The system is said to provide accurate measurements of diesel-fuel consumption in a range of industrial applications. End users employ fuel flowmeters to monitor diesel-fuel consumption in the automotive, marine, aerospace and power-generation industries.

For example, mining companies utilising diesel generators to power their operations require the accurate monitoring of diesel-fuel usage to ensure the efficiency and reliability of the generators. Flowmeters used in this application must be able to withstand extreme temperature swings in the installation environment. Pairing Flow Technology's FT Series turbine meter with the Linearlink temperature-compensated interface (TCI), the FT/DF system can accurately measure diesel fuel at temperatures as low as -50F.

The turbine flowmeter incorporates 'fail-open' technology, meaning that, in the event of a malfunction, fuel continues to be fed to the generator, ensuring that there is no interruption of power to the industrial operation. The FT Series turbine flowmeter relies on a proven flow-measurement technique to provide accurate and reliable digital outputs. As a result of its versatility, the FT meter is suitable for a variety of liquid and gas flow sensing applications.

The Linearlink TCI represents a sophisticated electronics platform for flowmeter linearisation and viscosity correction, according to the company. It is said to provide improvements in flow meter accuracy, even under extreme temperature conditions.
