Series 8000-8100MP
Inline Remote Thermal
Mass Flow Meter

This series meter is great for where agency approvals are required for Explosion Proof area locations.

Series 7000 Inline Thermal Mass Flow Switch

Inline flow switches are available in sizes  from 1/4″ pipe through 4″ pipe and are  provided with threaded male  NPT ends as the standard mounting style.  Optional end mounting styles may be specified.

Series 8200MPHT Insertions Remote Thermal Mass Flow Meter High Temperature

The EPI Model 8200MPHT series meters are great for high temperature applications where a remote enclosure is required. All EPI flow meters are equipped with a robust feature set with a wide selection of standard and normalized units of measure.

Series 8000-8100MPNH Inline Remote Thermal Mass Flow Meter

Inline style thermal mass flowmeters include a flow section that is usually specified to match the user’s flow conduit and is then plumbed directly into the process line. This design has the sensing elements mounted directly in the flow section for exposure to the process gas.

Series 8800MPHT Insertion Thermal Mass Flow Meter High Temperature

This series meter is great for high temperature applications. Insertion style thermal mass flowmeters include a sensor & probe assembly that is inserted into the process gas flow conduit to allow the process gas to flow across the flow sensing elements. Our insertion style flowmeters are available with 3/4″, or 1″ OD probes.

Thermal mass flow meters for a wide variety of applications

Master-Touch™ Family of Microprocessors

In many industries the need for monitoring gas flow does not involve hazardous gases or potentially dangerous operating conditions. These applications can include many water and wastewater treatment applications, the HVAC industry, the general use of compressed air, and many other applications using air, nitrogen, argon, etc. In these cases, an explosion-proof electronics enclosure is not required, and may be considered a needless expense. To meet this challenge, Eldridge Products, Inc. now offers the Master-Touch™ Family of microprocessor based thermal gas mass flowmeters… in a nonhazardous enclosure.

Thermal Gas Flow Meter Software

EPICommunicator™ (EPICom™) is proprietary software for use with any Master-Touch™ flow meter which has operating firmware V7.0ArA consists of four modules — EPITerm™, EPIMeter™, E-Logger™ and Modbus RTU — V7.0ArB adds Epi-Val™; which work together to put complete control of the Master-Touch™ flow meter in the hands of the user. EPICom uses the RS232, RS485 or USB communication protocol to connect a Master-Touc™ flow meter to a PC running Windows® software.
