		on the lowest-rated element, with regard to pressure, of the selected
		components, i.e. the process connection must be taken into consideration in

		lowest-rated element, with regard to pressure, of the selected components,
		i.e. the process connection has to be taken into consideration in addition to

	Example
	• Sensor: 10 bar (150 psi)					• Calibrated/Adjusted measuring span: 0...5 bar
	• Upper range limit (URL) = 10 bar (150 psi)					(0...75 psi)
						• Lower range value (LRV) = 0 bar
	Turn down (TD):					• Upper range value (URV) = 5 bar (75 psi)
	TD	=		URL
			|URV	-	LRV|

3.2Device designation

3.2.1 Nameplates

•The MWP (maximum working pressure) is specified on the nameplate. This value refers to a reference temperature of +20 °C (68°F) and may be applied to the device for an unlimited time. Observe temperature dependency of the MWP. The pressure values permitted at higher temperatures can be found in the standards EN 1092-1: 2001 Tab. 18 (With regard to their stability-temperature property, the materials 1.4435 and 1.4404 are grouped together under 13EO in EN 1092-1 Tab. 18. The chemical composition of the two materials can be identical.), ASME B 16.5a – 1998 Tab. 2-2.2 F316, ASME B 16.5a – 1998 Tab. 2.3.8 N10276, JIS B 2220.

•For PMD75, the MWP applies for the temperature ranges specified in the Technical Information TI00382P in the "Ambient temperature range" and "Process temperature limits" sections.

•The test pressure corresponds to the over pressure limit (OPL) of the device = MWP x 1.5.

•The Pressure Equipment Directive (2014/68/EU) uses the abbreviation "PS".

The abbreviation "PS" corresponds to the MWP (maximum working pressure) of the measuring device.

4.2Installation conditions

4.2.1 Dimensions

For dimensions, please refer to the Technical Information for Deltabar S TI00382P, "Mechanical construction" section.

4.3Installation instructions

•Due to the orientation of the Deltabar S, there may be a shift in the measured value, i.e. when the container is empty or partially full, the measured value does not display zero. You can correct this zero point shift using the "Zero" key on the electronic insert or externally on the device or via the onsite display. ä 27, Section 6.2.1 "Position of the operating elements",

ä 29, Section 6.2.3 "Function of the operating elements – onsite display connected" and

ä 37, Section 7.5 "Position adjustment"..

•For FMD77 and FMD78, please refer to Section 4.3.4 "Installation instructions for devices with diaphragm seals (FMD78)", ä 16.

•General recommendations for routing the pressure piping can be found in DIN 19210 "Methods for measurement of fluid flow; differential piping for flow measurement devices" or the corresponding national or international standards.

•Using a three-way or five-way valve manifold allows for easy commissioning, installation and maintenance without interrupting the process.

•When routing the pressure piping outdoors, ensure that sufficient antifreeze protection is used, e.g. by using pipe heat tracing.

•Install the pressure piping with a monotonic gradient of at least 10%.

•To ensure optimal readability of the onsite display, it is possible to rotate the housing up to 380°. ä 20, Section 4.3.9 "Rotating the housing".

•Endress+Hauser offers a mounting bracket for installing on pipes or walls.

ä 18, Section 4.3.7 "Wall and pipe-mounting (optional)".

4.3.1 Installation for flow measurement

Flow measurement in gases with PMD75

•Mount the Deltabar S above the measuring point so that the condensate can run off into the process piping.

Flow measurement in steam with PMD75

•Mount the Deltabar S below the measuring point.

•Mount the condensate traps at the same level as the tapping points and at the same distance to the Deltabar S.

•Prior to commissioning, fill the pressure piping to the level of the condensate traps.

Flow measurement in liquids with PMD75

•Mount the Deltabar S below the measuring point so that the pressure piping is always filled with liquid and gas bubbles can run back into the process piping.

•When measuring in media with solid parts, such as dirty liquids, installing separators and drain valves is useful for capturing and removing sediment.

4.3.2 Installation for level measurement

Level measurement in an open container with PMD75

•Mount the Deltabar S below the lower measuring connection so that the pressure piping is always filled with liquid.

•The negative side is open to atmospheric pressure.

•When measuring in media with solid parts, such as dirty liquids, installing separators and drain valves is useful for capturing and removing sediment.

Level measurement in an open container with FMD77

•Mount the Deltabar S directly on the container. ä 18, Section 4.3.5 "Seal for flange mounting".

•The negative side is open to atmospheric pressure.

Level measurement in a closed container with PMD75

•Mount the Deltabar S below the lower measuring connection so that the pressure piping is always filled with liquid.

•Always connect the impulse piping of negative side above the maximum level.

•When measuring in media with solid parts, such as dirty liquids, installing separators and drain valves is useful for capturing and removing sediment.

Level measurement in a closed container with FMD77

•Mount the Deltabar S directly on the container. ä 18, Section 4.3.5 "Seal for flange mounting".

•Always connect the impulse piping of negative side above the maximum level.

•When measuring in media with solid parts, such as dirty liquids, installing separators and drain valves is useful for capturing and removing sediment.

Level measurement in a closed container with FMD78

•Mount the Deltabar S below the lower diaphragm seal. ä 16, Section 4.3.4 "Installation instructions for devices with diaphragm seals (FMD78)".

•The ambient temperature should be the same for both capillaries.

Level measurement is only ensured between the upper edge of the lower diaphragm seal and the lower edge of the upper diaphragm seal.

Level measurement in a closed container with superimposed steam with PMD75

•Mount the Deltabar S below the lower measuring connection so that the pressure piping is always filled with liquid.

•Always connect the impulse piping of negative side above the maximum level.

4.3.3 Installation for differential pressure measurement

Differential pressure measurement in gases and steam with PMD75

•Mount the Deltabar S above the measuring point so that the condensate can run off into the process piping.

Differential pressure measurement in liquids with PMD75

•Mount the Deltabar S below the measuring point so that the pressure piping is always filled with liquid and gas bubbles can run back into the process piping.

•When measuring in media with solid parts, such as dirty liquids, installing separators and drain valves is useful for capturing and removing sediment.

Differential pressure measurement in gases, steam and liquids with FMD78

•Mount the diaphragm seal with capillaries at the top or on the side on the piping.

•For vacuum applications: mount the Deltabar S below the measuring point. ä 17, Section 4.3.4, "Vacuum application (FMD78)".

•The ambient temperature should be the same for both capillaries.

4.3.4 Installation instructions for devices with diaphragm seals (FMD78)

•Please note that the hydrostatic pressure of the liquid columns in the capillaries can cause zero point shift. The zero point shift can be corrected.

•Do not clean or touch the process isolating diaphragm of the diaphragm seal with hard or pointed objects.

•Do not remove process isolating diaphragm protection until shortly before installation.

NOTICE

Improper handling!

Damage to the device!

A diaphragm seal and the pressure transmitter together form a closed, oil-filled calibrated system. The fill fluid hole is sealed and may not be opened.
