Eldridge Products, Inc. (EPI) products

Part of the SWITCH product family that are different than thermal mass flow meters, the Series 7000 is a thermal mass flow switch that detects the presence of the flow, at a predetermined set point, sends alerts, and performs designated actions. Designed with inline installation type, these thermal mass 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. While the Series 7000 is designed with an explosion-proof enclosure for Hazardous locations, the model has still not been submitted for agency approval testing. To provide you with accurate measurements and detection, the Series 7000 uses our proprietary temperature compensation techniques with a sensor assembly that utilizes two RTD (Resistance Temperature Detector) sensing elements. 

Approved for Hazardous Locations, the Series 8000-8100MP Inline Remote Thermal Mass Flow meters are a brilliant choice for all environments. Accessible in an Inline system with Remote Electronics, this series provides you with a multitude of possibilities to suit most conditions you may need it for, wherever you may require. The unique Remote Style Thermal Mass Flow Meter option uses two enclosures, one attached at the point of measurement on the flow section, on the probe assembly, and the second – which is the remote access portion, which can be positioned in a more manageable monitor location. The sensors provided are temperature compensated for a wide process gas temperature range which means you can be confident that your interpretations and output signal are a true monitor signal.

Part of EPI Flow’s PURE series of clean hygienic flow meters, the EPI-PUREGEN-LM Series 800 HPX is an inline high purity thermal mass flow meter that uses an Explosion-Proof Rated Enclosure, for applications where extremely accurate and highly repeatable measurement and control is needed. The 800 HPX is a thermal mass flowmeter with a unique feature set specifically designed for a variety of Ultra High Purity and High Purity applications including Semiconductor & Displays, Pharmaceutical, Biotechnology, Food & Beverage, and other processes that require a clean hygienic flow meter.

Featuring a flow section quantified to match the user’s flow channel and plumbed directly into the process line, the Series 8600-8700 MP Flow meters provide you with the ultimate reliability, precision, and consistency required when dealing with monitoring thermal mass. Offering an Inline style and an integral style configuration that includes all the electrical components and connections in one enclosure for ease of use and simple monitoring, the series 8600-8700 offers you flexibility and consistency regardless of purpose. Utilizing state-of-the-art technology that makes optimal use of the principle of convective heat transmission to accurately and professionally measure mass flow, these exceptional and specialized Thermal Mass Flow Meters feature numerous thermal mass flow sensors that are high quality and unswervingly effective.

Flawless for usage in hazardous areas, the Master-Touch™ Series 9700MP thermal mass flow meters are an indispensable piece of equipment to provide you with precise and dependable thermal monitoring. Offering an Inline style thermal mass flow design that features the sensing elements openly mounted on the flow suction, the Inline style of the Series 9700MP Flow Meter is available in sizes from 2” pipe through to 4” pipe and can be provided with flanged end arrangements if necessary. The Series 9700MP is offered in an Integral Style that makes readings exceedingly simple by providing all the electrical apparatuses and mechanisms in a centralized location in an enclosure. A simple yet refined system, the Series 9700MP is an essential piece of engineering.
