In many industries the need for monitoring gas flow involves hazardous gases, potentially dangerous operating environments or simply a desire for a rugged, industrial-strength configuration. These applications include many common manufacturing processes, natural gas metering, compressed air auditing, etc. The Master-Touch MP Series is now approved for use in hazardous area locations:
Class I Division 1 Groups B, C and D; Class II E, F and G; Class III; Type 4X, 7; Ex d IIB + H2; AEx d IIB + H2, IP66; EEx d IIB + H2, IP66; T2 (consult factory for T3 or T4).
Certified to US requirements; Certified to Canadian requirements
Certified to European ATEX requirements
The remote enclosure is certified for use in Ordinary (Non-Hazardous) area locations:
Type 4X, IP66
EPI’s Master-Touch flowmeters incorporate the following subsystems to perform signal processing functions: sensor, bridge controller, microcomputer, and I/O communication outputs. Our proprietary microcomputer performs digital signal processing (DSP) functions utilizing a high speed, high resolution 16-bit analog to digital converter (ADC), a central processing unit (CPU) and a high resolution 14-bit digital to analog converter (DAC). Our CPU is an embedded microprocessor including random access memory (RAM), read-only memory (ROM), a serial communications controller (SCC), and I/O data lines.
In addition to the basic Run Mode for day-to-day operations, the Master-Touch includes a menuing system that is accessed via the 4-button keypad or a PC running EPICommunicator software, and now features eight operational menus with their submenu items:
100 *Meter* Menu This menu is used change the displayed engineering units, change the scaling of the output signals, and reset the stored values for elapsed total, high and low flow rates, timestamps, etc.
200 *Utility* Menu This menu is used to change a variety of microprocessor parameters, such as the display update rate, the internal date and time, the analog-to-digital (ADC) and digital-to-analog (DAC) signal conversion filters, etc.
300 *Status* Menu This menu includes a series of submenus which present basic information about the flowmeter set up and status.
400 *Alarms* Menu This menu is used to control the relay options, including pulsed outputs, high/low trip points, etc.
450 *E-Log* Menu This menu is accessed via EPICommunicator’s E-Logger module to perform datalogging functions.
700 *S-Curve Fit* Menu This menu is used to modify the factory calibration with a set of secondary coefficients based on customer data.
750 *PW-Curve Fit* Menu This menu is used to make adjustments to the linear output signal at specific 5% intervals of the calibrated full scale flow rate.
800 *P-Curve Fit* Menu This menu is used to access the global C-Factor, change the stored cross-sectional area value, etc.
You may download the Instruction Manual (see below) or go to our EPICommunicator page for a complete discussion of these features.
In the Master-Touch MP Series, the electronics enclosure at the point of measurement is approved for hazardous locations. In our integralstyle flowmeters, these electronics include all components including the flow rate and total display as well as a four-button keypad. Although our standard remote style configurations have a general purpose enclosure for installing at some distance from the point of measurement, explosion-proof enclosures for the remote electronics are also available.
