KEP meter MS-748 Rugged, Vehicle Mount, Multi-Function Flow Computer


The MS-748 Flow Computer satisfies the instrument requirements for a variety of flowmeter types in liquid, gas, steam and heat applications. Multiple flow equations are available in a single instrument with many advanced features. The alphanumeric display offers measured parameters in easy to understand format. Manual access to measurements and display scrolling is supported The versatility of the Flow Computer permits a wide measure of versatility within the instrument package.

The various hardware inputs and outputs can be “soft” assigned to meet a variety of common application needs. The user “soft selects” the usage of each input/output while configuring the instrument. Consider the following illustrative examples. The isolated analog output can be chosen to follow the volume flow, corrected volume flow, mass flow, temperature, pressure, or density using a menu selection. Most hardware features are assignable by this method.

The user can assign the standard RS-232 Serial Port for external data logging, transaction printing, or for connection to a modem for a remote meter reading. A Service or Test mode is provided to assist the user during startup system check out by monitoring inputs and exercising outputs. The system setup can also be printed.
