2.1 Introduction to the transmitters
The Mobrey MSP400RH and Mobrey MSP900GH are 4–20 mA loop-powered transmitters, and
are designed for liquid level measurement applications.
2.2 Theory of operation
The Mobrey MSP400RH and MSP900GH ultrasonic liquid level transmitters are mounted above
a liquid and use ultrasonic pulses to continuously measure the distance to the liquid surface. The
electronics calculate the distance to the liquid level using the time delay between transmitting
and receiving signals (Figure 2-1).
When programmed with the bottom reference of the application – usually the bottom of a tank
– the transmitter calculates the liquid depth (level), and outputs the result as a 4–20 mA signal
and a digital HART®signal.
The MSP400RH and MSP900GH can also calculate contents volume or open channel flow, when
programmed with further application information, and then outputs the result as a
4–20 mA signal and a digital HART signal.

2.3 Components of the transmitter
The transmitter has a housing containing advanced electronics to generate ultrasonic pulses,
process the resultant signals, and provide a 4–20mA and HART output.
Removing the lid reveals terminals to connect a cable (not supplied) for the signal output and
an external power supply. An LCD inside the enclosure displays the selected measurement.
Programming is achieved using integral buttons or by remote communication using HART.

B. 2-in. Mounting Thread D. M20 Conduit Threads
2.4 System architecture
The Mobrey MSP400RH and MSP900GH are two-wire, 24 Vdc loop-powered transmitters and
can be connected to a direct current (dc) power source using two-core, shielded cable.
The output can be a 4–20 mA analog signal and a digital HART signal.
Note
It is possible to use the multi-drop function with the HART protocol. In this case,
communication is restricted to digital since the current is fixed to 4 mA.
Each transmitter can be configured locally using the membrane-buttons which are revealed
after removing the housing cover. The transmitters can be configured remotely by using a
Mobrey MCU900 Series control unit
A comprehensive specification for the Mobrey MSP400RH and MSP900GH is in the section

3.2 Considerations before installation
The Mobrey MSP400RH and MSP900GH transmitters can be used for level and contents volume
measurements in open or closed tanks, or for open channel flow measurements.
The transmitter must be installed in a location where it is protected from ultraviolet radiation to
prevent long term degradation of the plastics used e.g. shrouded from direct sunlight.
It is important to correctly position the transmitter for reliable ultrasonic level measurement.
For maximum accuracy and stability of the level measurement reading, the transmitter should
always be shrouded from direct sunlight and radiated heat.
The transmitter may be site-tuned to deal with most application conditions, but it is
recommended that the following guidelines be adopted where relevant.
3.2.1 Safety considerations
Guidelines
1. Installation must be carried out by suitably trained personnel in accordance with the
applicable code of practice.
2. If the equipment is likely to come into contact with aggressive substances, it is the
responsibility of the user to take suitable precautions that prevent it from being
adversely affected, thus ensuring that the type of protection is not compromised.
Aggressive substances are acidic liquids or gases that may attack metals or solvents
that may affect polymeric materials.
Suitable precautions are regular checks as part of routine inspections, or establishing,
from the material's datasheet, that it is resistant to specific chemicals.
3. The equipment must only be cleaned with a damp cloth.
4. The equipment is not intended to be repaired by the user and is to be replaced by an
equivalent certified unit. Repairs should only be carried out by the manufacturer or
approved repairer.
5. The transmitter is double insulated, and therefore Protective Earthing is not required.
However, the cable shield/screen should be connected to a suitable ground (earth) at
one end only (see “Connecting the cable(s) to the transmitter” on page 16).
6. Note that if the equipment is used in a manner not specified by the manufacturer, the
protection afforded by the equipment may be impaired.
7. To ensure electro-magnetic compatibility in any European member state, it should not
be installed in a residential area.
Note
It is not advisable to mount the transmitter in close proximity to a source of electrical
noise such as a variable-speed drive, or other high-powered electrical device.

3.3 Mechanical installation
Guidelines
1. Mount the transmitter above the liquid surface using the 2-inch thread provided, but
not closer than 12 in. (0,3 m) to the surface. The transmitter does not detect any liquid
surface closer than 12 in. (0,3 m) to the transmitter face. (See “Mounting the
transmitter above the liquid surface” on page 11).
Optional flanges and bracket kits are available to help mounting. (See Delta Mobrey
product data sheet IP2045 for accessory part numbers.)
2. The transmitter should be mounted vertically toensure a good echo from the liquid
surface. The transmitter beam half angle of the is 6 degrees. (See Figure 3-1 on
page 10).
3. Obstructions in the tank, or well, may generate echoes which can be confused with the
real liquid surface echo. Obstructions within the beam angle generate strong false
echoes. Wherever possible, the transmitter should be positioned toavoid false echoes.
4. To avoid detecting unwanted objects in the tank or well, it isadvisable to maintain a
distance of atleast 1.3 in. from the center line of the transmitter for every foot (11 cm
per meter) range to the obstruction.
5. No false echoes are generated if the transmitter islocated near the side of the tank or
well, and the wall is smooth and free of protrusions. However, there will still be a
reduction in the echo size. It is recommended that the transmitter be mounted no
closer than 12 in. (0,3 m) to the wall toavoid a large reduction in the echo size.
6. If the transmitter is mounted in an enclosed tank with a domed top, avoid mounting
the transmitter in the center of the tank roof because this could act as a parabolic
reflector and create unwanted echoes.
7. Avoid applications where heavy condensation could form on the transmitter face.
8. If the transmitter is mounted in a stand-off or nozzle, the transmitter face should
protrude at least 0.2 in. (5 mm) into the tank. If this is not possible, see “Mounting the
transmitter above the liquid surface” on page 11).
9. If the transmitter is used in environments where direct sunlight can cause high surface
temperatures on exposed surfaces, a sun-shade is recommended.
10. Check that the maximum liquid level will not enter the 12-in. (0,3 m) blanking zone of
the transmitter.

C. 6° beam half angle
D. 1.3 in./ft. (11 cm/m). Minimum of 12 in. (0.3 m).
3.3.1 Consider the liquid surface conditions
Guidelines
1. Foaming liquids can reduce the size of the returned echo because foam is a poor
ultrasonic reflector.
Mount an ultrasonic transmitter over an area of clear liquid, such as near the inlet to a
tank or well. In extreme conditions, or where this is not possible, the transmitter may
be mounted in a vented stilling tube provided that the inside measurement of the
stilling tube is at least 4 in. (100 mm) and is smooth and free from joints or protrusions.
It is important that the bottom of the stilling tube stays covered to prevent the ingress
of foams.
2. Avoid mounting the transmitter directly over any inlet stream.
3.3.2 In-tank effects
Guidelines
1. Stirrers or agitators can cause a vortex. Mount the transmitter off-center of any vortex
to maximize the return echo.
2. If stirrer blades become uncovered, they create echoes as they pass through the
ultrasonic beam. The transmitter can learn to ignore these false echoes (see page 56 or
page 93 for further information).
