INTRODUCTION

1 INTRODUCTION

Michell Instruments designs and manufactures a broad range of sampling systems for a wide spectrum of industries and processes from the economical compressed air market to the oil and gas process market.

Sample extraction, handling and conditioning techniques are of critical importance to assure optimal performance and reliability of all analysers which accurately quantify speciﬁ c components within a process gas or liquid composition. With a wide variety of options required for pressure and ﬂ ow control, ﬁ ltration, isolation and sample temperature control it can be difﬁ cult to see what is really required to get maximum performance from your analysers in any given application.

The ES70 series is designed to simplify sample system conﬁ guration by providing a set of choices for all requirements, such as panel or enclosure mount, ﬁ ltering, upstream and downstream pressure and ﬂ ow control etc. This provides a quick and simple method to choose all the required components suitable for the application requirements.

1.1 Materials

ES70 User’s Manual

To ensure continuous and reliable dew-point or moisture measurement it is important that the dew-point transmitter is exposed to stable conditions of the gas to be monitored.

The ES70 systems utilizes high quality materials which ensure that the sample gas travels smoothly through the system.

Gas wetted parts:

• Stainless steel tube, ﬁ lter housing and ﬁ ttings (316 stainless steel)

• Filter element (oleo-phobic membrane or stainless steel mesh)

• Single- or dual-stage pressure reduction

• Transmitter sample block (316 stainless steel)

• Flowmeter (borosilicate glass) with Viton® seals or high-pressure rated armored type

1.2 System Designs

Our sampling system designs ensure that dew-point and moisture measurements can be performed in the most suitable conditions. The ES70 sampling systems can be supplied in various conﬁ gurations and are designed to be used in conjunction with other Michell products, as follows:

• Easidew PRO XP Transmitter

• Easidew PRO I.S. Transmitter (with or without display)

• Promet I.S. (with or without pressure transmitter)

• Liquidew I.S.

Process connections are available with either 6mm or 1/4” tube ﬁ ttings.
