Flow Technology, Inc. Liquid/Gas Flow Computer SL9000

The SL Series Flow Computers consist of three panel-mounted display units for use with liquid and gas flowmeters. All units are easily programmed through the front keypad or with a Windowsbased PC software program. Each device has multiple assignable outputs allowing tremendous flexibility to set the units up for analog output, batch control and alarms. The display on the flow computers is an easy to read, two-line, twenty-character backlit LCD with a character height of three-tenths of an inch. Measured and calculated parameters can be assigned to the display in an easy to understand format. Application The SL9000 Flow Computer is capable of 16-point linearization, providing high accuracy when used with flow meters calibrated over their full extended range. It is designed for use in volumetric liquid and gas applications where temperature and pressure compensation are not required. The SL9100 is designed for liquid applications where compensation is required for variation in fluid operating temperature. The unit can be configured to display volumetric or mass units of measure with UVC and Strouhal – Roshko temperature compensation for variations in viscosity and density due to temperature. The SL9200 Flow Computer has the same temperature compensation capability for liquid applications as the SL9100, plus the ability to provide pressure and temperature compensation for gas applications. The absolute viscosity of the gas is corrected for variation in temperature and the density of the gas is calculated using temperature and pressure measurements. The SL9200 can display and output compensated volumetric data in actual or standard units as well as mass units of measure.
