Flow Measurement & Control


Flowmeter with portable or fixed installation option

September 2000 Flow Measurement & Control

Claimed by its makers to be the world’s most advanced portable transit time flowmeter, the DCT7088 combines digital signal processing (DSP) with correlation detection methods, this results in exceptional performance and flexibility.

While principally designed for clean liquid applications, the instrument is tolerant of liquids with higher concentrations of entrained solids or gas bubbles than was previously possible with transit time technology. The nonintrusive, clamp-on transducers can be installed without flow interruption and insure leak-free measurements with zero pressure drop. The simple menu-driven operation of the DCT7088 allows speedy configuring of the meter.

Housed in a rugged NEMA-6 (IP67) enclosure, the DCT7088 is waterproof against accidental immersion and splash-proof with the lid open. The display is a high resolution, backlit LCD providing good visibility, even in poorly lit conditions. Outputs include a 12 bit, 4 to 20 mA analog signal and RS232 serial interface.

The flowmeter also incorporates a powerful data logger that can record up to 65 000 data points for subsequent uploading to a personal computer. A separate memory function stores up to 16 sets of site parameters, eliminating the need to re-enter setup data when returning to a location for further measurements.

The DCT7088 can be programmed to start and finish flow measurements at predetermined times for unattended operation. In addition to password protection, a padlock can be attached to the instrument enclosure to avoid any chance of unauthorised tampering. The meter will provide up to 16 hours of continuous battery operation and can be fully recharged in only eight hours. There is no need for multiple transducers for different pipe materials and sizes, as the standard transducer set is suitable for most plastic, metal and even concrete-lined pipes, and for diameters from 1" (25 mm) to 200" (5 m).

The meter is supplied with an impressive array of optional accessories. The UTG is a compact and rugged, ultrasonic thickness gauge, which allows pipe wall thickness to be quickly determined from the outside of the pipe. As an instrument separate from the DCT7088, the UTG can be used for other functions such as measuring the corrosion or erosion of storage tank walls, etc. To provide an immediate paper record of individual flow measurements, logged data and/or site parameters, a small thermal printer is also available.

The TimeGate program supplied with each DCT7088 is a configuration and signal analysis program. While not necessary to set up or operate the instrument, it offers a simple, Microsoft Windows-based method to configure the flowmeter and access the extensive waveform diagnostics available from the DCT7088. Featuring easy-to-use pull-down menus and pop-up windows, it provides a rapid and versatile means to select the ideal transducer location in marginal applications. Stored site and configuration data can also be downloaded to one or more instruments, thus eliminating the need to individually program multiple meters. It also provides a paperless method of retaining and archiving the calibration data - simplifying the data retention and reporting requirements necessary for ISO9000, OSHA and FDA compliance.

Applications:

HVAC, potable water, ultrapure liquids, de-ionised water, petroleum products, water and waste management.

Features:

Accuracy to ±0,5%; flow sensitivity 0,001 ft/s (0,3 mm/s); NEMA-6 environmental sealing; easy to install; clamp-on design; bi-directional flow measurement; powerful 65 000 point data logger; TimeGate diagnostics and waveform analysis.

Fixed installation

Titan Technology also offers the DCT6088 for permanent installations. Housed in a rugged NEMA-4X (IP65) enclosure and qualified for -40°C operation, the DCT6088 is well suited to most industrial environments. The standard display is a high resolution, backlit LCD providing excellent visibility, even in poorly lit conditions. A vacuum fluorescent display is also optionally available for installations where a wide viewing angle or reading from a distance is necessary. Outputs include a 12 bit digital, optically isolated, 4-20 mA analog signal and RS232 serial interface.
