Description

Delta-Elektrogas MG Pressure Gauge for Gas

Delta-Elektrogas MG Pressure Gauge for Gas are robust instruments suitable for fast measurement on site. Different dimensions and materials allow us to find the proper solution for every installation. Delta-Elektrogas MG Pressure Gauge for Gas is available with display dimensions Ø63, Ø80, and Ø100. A button valve type ME can be installed to prevent damage due to pressure surges.

In 1961 Elettromeccanica DELTA s.p.a. was founded in Arcade (TV) with the aim of designing and manufacturing oil burners with mechanical atomization. Today, Elettromeccanica DELTA and its brand Deltapumps and Elektrogas are leading manufacturers of gear oil pumps and safety control valves, exported in more than 60 countries in the world.

Technical Overview & Operation

The Delta-Elektrogas MG Pressure Gauge for Gas operates using high-sensitivity mechanical measuring elements tailored to line pressure ranges. Low-pressure variants utilize a sensitive copper alloy capsule element, while higher-pressure versions employ a C-shaped Bourdon tube.

When gas pressure enters the threaded connection port, it expands the internal capsule or Bourdon tube. Precision clockwork movements translate this displacement into smooth, accurate pointer deflection across a high-contrast dual-scale dial ( $mbar / kPa$ or $bar / PSI$ ). Housed in a steel or die-cast casing with a shatterproof acrylic window, the MG series isolates internal mechanisms from dust, vibration, and ambient plant moisture. Available in bottom-entry (radial) or back-entry (axial) mounting configurations with standard 1/4″ or 1/2″ NPT/BSP threads, it fits directly into gas valve manifolds, pressure regulators, and pipeline test ports.

Version and media type Standard version for air and Stainless steel version gaseous fuels in accordance for chemically aggressive with EN437 (fam. 1-2-3) gaseous fuels (e.g. Biogas)

Materials in contact Brass AISI 304 with media Bronze AISI 316

ME button valve

Connection (female thread) G1/4, G3/8, G1/2
Ambient and media temperature -20°C / +60°C
Maximum operating pressure 6 bar
Materials in contact Brass and NBR rubber with media Suitable only for air and gaseous fuels in accordance with EN437 (fam. 1-2-3)

Features

These pressure gauges are available with display dimension Ø63, Ø80 and Ø100. The connection is radial with male thread ¼” for Ø63, 3/8” for Ø80 and ½” for Ø100.
Manometers are capsule types for pressure till 600 mbar, for higher pressure they have a Bourdon tube.
They are designed in compliance with EN 837-1 and 3.
The accuracy is ± 1,6% of full scale.
They are suitable for ambient temperature -20/+60°C. If temperature of process medium is
higher, proper devices shall be used to cool it before reaching the instrument (e.g. dissipators,
capillaries).
Continuous operating pressure can be max 75% of full scale.
ME valve is a push-button valve which applies pressure to gauge only when it is pushed, in
normal condition manometer is relieved of pressure. The installation of this valve extends life of pressure gauge and reduces possibilities of wrong reading (e.g. in case of dirty the pressure
gauge can block in a position different from actual pressure).
Suitable for air and non-aggressive gaseous fuels (families 1-2-3 EN437). Special versions are
available for use with aggressive gases (e.g. biogas).
This figure shows an example of typical installation in combination with other Elektrogas
devices.
