Thermo Scientific DCT7088

Portable, Digital-Correlation,
Transit-Time Flowmeter

The powerful Thermo Scientific DCT7088
portable, digital-correlation, transit-time
flowmeter is the most durable meter
of its kind. Housed in a virtually
indestructible, waterproof carrying
case, this user-friendly device features
a 40,000-point data logger and a
memory function that stores four sets
of site parameters to simplify
installation and ongoing operation.

The advanced Thermo Scientific DCT7088
portable transit-time flowmeter combines
digital signal processing (DSP) with
correlation detection methods to measure
velocity, flow rate and volumetric flow.
Principally engineered 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
technolo

gy. Unlike competitive transit-time
flowmeters,
required for different pipe materials and
sizes. The standard transducer set is
suitable for most plastic, metal and even
concrete-lined pipes that range in size from
1 inch (25.4 mm) to 200 inches (5 m). Pipes
measuring less than 2 inches may require
smaller transducer housing assemblies. The

Outputs include a 4-20 mA analog signal
and RS232 serial interface. A powerful
40,000-point data logger enables users
to quickly upload process data to a laptop
or personal computer. A separate memory
function stores up to four sets of site
parameters, eliminating the requirement

Simple menu-driven operation enables
the DCT7088 flowmeter to be configured
in a fraction of the time necessary for
competitive transit-time flowmeters, and
it is programmable to start and finish flow
measurements at predetermined times for
unattended operation. The meter provides up
to 16 hours of continuous battery operation
and ful
