    EPICommunicator™

    EPICommunicator™ (EPICom) is proprietary software for use with any Master-Touch™ flowmeter which has V3.9G or later software. It consists of four modules — EPITerm, EPIMeter, E-Logger™ and Modbus RTU — which work together to put complete control of the Master-Touch flowmeter in the hands of the user. EPICom uses the RS232, RS485 or USB communication protocol to connect a Master-Touch flowmeter to a PC running Windows XP® / Vista®.

    Flow Averaging Tubes (FAT™)

    MP Series FAT™ flowmeters are approved for use in hazardous locations. Series 9100MP-9200MP instruments have an explosion-proof flow transmitter mounted at the point of measurement with the signal processor electronics remotely mounted in a separate, general purpose enclosure. An explosion-proof enclosure for the remote electronics is available as an option. The Series 9700MP-9800MP instruments have all electronics mounted at the point of measurement in an explosion-proof enclosure.

    Flow Switches

    Eldridge Products, Inc. (EPI) Series 7000, 7100, and 7200 Flow Switches are rugged flow switches for gases. Our flow switches are built with the same components as our flowmeters and operate on the same prinicpals of thermal dispersion. They include two High/Low relays for High/High, Low/Low, and Low/High switch options. One second to thirty seconds time delay is a available as a standard, with automatic reset in one second upon resumption of non-fault flow conditions. Two LEDs provide verification that an alarm has been triggered. The flow switches are calibrated for your process conditions and the relay trip points can be easily set up in the field. Factory calibrated trip points are also available, at an additional charge.

    LightWIRE™ Infrared Modules

    The LightWIRE Communicator I modules can transmit and receive signals from both LightWIRE enabled flowmeters and LightWIRE Communicator III modules. When connected to a RS232 or USB port on a PC or laptop running EPI Communicator software, the LightWIRE Communicator I module replaces the three-wire cable for communications with an IR-Enabled Master-Touch™ flowmeter.

    Master-Touch™ Multipoint Systems

    Eldridge Products, Inc. (EPI) Series 9000MP Multipoint Thermal Mass Flowmeter Systems are designed to measure air and gas flow in Thermal Mass Flowmeter Systems where two or more sensing points are required due to large cross-sectional areas. The Series 9000MP Multipoint Thermal Mass Flowmeter System now incorporates our newest Master-Touch microprocessor technology. This advancement provides the user with unrivaled control, power, and flexibility for measuring flows in large ducts, stacks, and flow conduits. The Series 9000MP Multipoint Thermal Mass Flow Meter Systems have a sensor accuracy of ± (1% of reading + .5% of full scale) over a calibration turndown ratio of 100:1 or more, based on velocities as low as 15 SFPM (.076 NMPS) and as high as 20,000 SFPM (101.6 NMPS).
