 EPI Series 7000 Inline Thermal Mass Flow Switch

EPI 2

 

Description

The Eldridge Product,Inc. (EPI) Inline style thermal mass flow switch series 7000 assembly includes the flow sensing element, temperature sensing element, bridge amplifier/signal output board, transmitter enclo­sure, and flow section. The flow section is typically specified to match the user’s flow conduit and is plumbed directly in the flow line. This design has the sensing elements mounted directly in the flow section for exposure to the process flow.

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, such as tube ends, tube end fittings, butt weld ends, flanged end configurations, etc. as required. Pipe sizes in excess of 4″ require insertion style thermal mass flow switches.

All of EPI’s flow switches have two single-pole, double-throw relays for Hi/Hi, Lo/Lo and Hi/Lo capability. The contact closure is 5 amps @ 24 VDC and 115 VAC. Two LEDs are provided for verification that the Hi or Lo alarm has been triggered. The standard configuration has 316 Stainless Steel wetted parts (Hastelloy & Monel are also available) for a rugged, cleanable instrument designed for use in applications where corrosion, abrasion, high pressure or rough handling may be expected


 EPI Series 8000-8100MP Inline Remote Thermal Mass Flow Meter

EPI3

Description

The Eldridge Product,Inc. (EPI) Inline style thermal mass flow meter series 800-8100MP includes 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. Our inline style thermal mass flow meters are available in sizes from 1/4″ pipe through 4″ pipe or tube, and are provided with a variety of options such as MNPT ends, tube end fittings, butt weld ends, flanged end configurations, etc. as required. Pipe sizes in excess of 4″ typically require insertion style thermal mass flow meters.

Remote style thermal mass flow meters utilize two enclosures. One enclosure is mounted at the point of measurement on the flow section or on the probe assembly. This enclosure may be rated for either hazardous environments or for ordinary, non-hazardous environments, as necessary. The second (remote) enclosure is usually placed in a readily accessible location rated for non-hazardous conditions. (Contact the factory for information concerning remote explosion-proof enclosure). The remote enclosure includes the all of the electrical connections as well as the linearizing electronics and the display/keypad assembly. Only a four-wire, twisted-pair cable is required to carry the input power and flow signal between the two enclosures.

Thermal mass flow meters use the principle of convective heat transfer to directly measure mass flow. EPI’s proprietary thermal mass flow sensors use two ratiometrically-matched, reference-grade platinum Resistance Temperature Detectors (RTDs). The platinum sensing element wire is encapsulated in a 316 Stainless Steel sheath or, if specified, a Hastelloy C sheath. Our microcontroller operated smart sensor technology preferentially heats one RTD; the other RTD acts as the temperature reference. The process gas flow dissipates heat from the first RTD, causing an increase in the power required to maintain a balance between the RTDs. This increase is directly related to the gas molecular rate of flow. Our sensors are temperature compensated for a wide process gas temperature range and insensitive to pressure changes, so the output signal is a true mass flow rate signal.

This design has the sensing elements mounted directly on the flow section for exposure to the process gas. Our inline style flow averaging thermal mass flow meters are available in sizes from 2″ pipe through 4″ pipe and are provided with flanged end configurations, as required. Pipe sizes in excess of 4″ typically require insertion style thermal mass flow meters.

Remote style thermal mass flow meters utilize two enclosures. One enclosure is mounted at the point of measurement on the flow section or on the probe assembly. This enclosure may be rated for either hazardous environments or for ordinary, non-hazardous environments, as necessary.

The remote enclosure includes the all of the electrical connections as well as the linearizing electronics and the display/keypad assembly.

Our patented Flow Averaging Tubes™ (FAT™) use the principle of convective heat transfer to directly measure mass flow, and are well suited to most applications with limited available straight run. In many installations, the up-stream straight run can be reduced to three diameters. The probe has a number of large diameter inlet ports along the length of the upstream impact surface. The pressure at each inlet port is averaged inside the tube to create the axial flow through the tube and across our flow sensor. The gas returns to the main flow stream through the ports located near the sensing elements. Anomalies in the actual flow profile or installations in non-circular ducts may still some require minor adjustment to achieve the best accuracy.
