Preferably install the sensor in an ascending pipe, and ensure a sufficient distance to the
next pipe elbow: h ≥ 2 × DN

Installation in down pipes

Install a siphon with a vent valve downstream of the sensor in down pipes whose length h
≥ 5 m (16.4 ft). This precaution is to avoid low pressure and the consequent risk of
damage to the measuring tube. This measure also prevents the system losing prime.

1) Applications with low process temperatures may decrease the ambient temperature. To maintain the

minimum ambient temperature for the transmitter, this orientation is recommended.

2) Applications with high process temperatures may increase the ambient temperature. To maintain the

maximum ambient temperature for the transmitter, this orientation is recommended.

3) To prevent the electronics module from overheating in the case of a sharp rise in temperature (e.g. CIP- or

SIP processes), install the device with the transmitter component pointing downwards.

Horizontal

A0025817

1 Measuring electrodes for signal detection

Ideally, the measuring electrode plane should be horizontal. This prevents brief
insulation of the two measuring electrodes by entrained air bubbles.

Valves

Never install the sensor downstream from a filling valve. If the sensor is completely empty
this corrupts the measured value.

Correct measurement is only possible if the pipe is completely full. Perform sample
fillings before commencing filling in production.

Adapters

Suitable adapters to DIN EN 545 (double-flange reducers) can be used to install the sensor
in larger-diameter pipes. The resultant increase in the rate of flow improves measuring
accuracy with very slow-moving fluids. The nomogram shown here can be used to
calculate the pressure loss caused by reducers and expanders.

The nomogram only applies to liquids with a viscosity similar to that of water.

1. Calculate the ratio of the diameters d/D.

2. From the nomogram read off the pressure loss as a function of flow velocity
(downstream from the reduction) and the d/D ratio.

6.1.3 Special mounting instructions

6.2 Mounting the measuring device

6.2.1 Required tools

For sensor

Endress+Hauser 21

For flanges and other process connections:

• Screws, nuts, seals etc. are not included in the scope of supply and must be provided by
the customer.

• Appropriate mounting tools

6.2.2 Preparing the measuring device

1. Remove all remaining transport packaging.

A0003762

Installation Dosimag Modbus RS485

2. Remove any protective covers or protective caps present from the sensor.

3. Remove stick-on label on the electronics compartment cover.

6.2.3 Mounting the measuring device

WARNING

L

Danger due to improper process sealing!

Ensure that the inside diameters of the gaskets are greater than or equal to that of the

‣

process connections and piping.
Ensure that the gaskets are clean and undamaged.

‣

Install the gaskets correctly.

‣

Depending on the order option, the measuring device is supplied with or without pre­installed process connections. Pre-installed process connections are secured to the
measuring device using 4 hexagonal-headed bolts.

Ensure that the direction of the arrow on the nameplate of the sensor matches the flow

‣

direction of the fluid.

Depending on the application and pipe length, the measuring device may need to be
supported or additionally secured.

6.2.4 Welding the sensor into the pipe (welding connections)

WARNING

L

Risk of destroying the electronics!

Make sure that the welding system is not grounded via the sensor or transmitter.

‣

1. Tack-weld the sensor to secure it in the pipe. A suitable welding jig can be ordered
separately as an accessory →  74.

2. Release the screws on the process connection flange and remove the sensor, along
with the seal, from the pipe.

3. Weld the process connection into the pipe.

4. Reinstall the sensor in the pipe, and in doing so make sure that the seal is clean and
in the right position.

• If thin-walled pipes carrying food are welded correctly, the seal is not damaged by
the heat even when mounted. However, it is recommended to disassemble the
sensor and seal.

• It must be possible to open the pipe by approx. 8 mm (0.31 in).

6.2.5 Cleaning with pigs

It is essential to take the internal diameters of the measuring tube and process connection
into account when cleaning with pigs. All the dimensions and lengths of the sensor and
transmitter are provided in the separate "Technical Information" document.

22 Endress+Hauser

Dosimag Modbus RS485 Installation

6.2.6 Seals

When mounting the process connections, make sure that the seals in question are dry,
clean, undamaged and correctly centered.

• The screws must be firmly tightened. The process connection forms a metal
connection with the sensor, which ensures a defined compression of the seal.

• Depending on the application the seals should be replaced periodically, particularly
if molded seals are used (aseptic version)!
The interval between changes depends on the frequency of the cleaning cycles, the
cleaning temperature and the medium temperature.
Replacement seals can be ordered as an accessory.

6.2.7 Nominal diameter and flow

The diameter of the pipe and the flow rate determine the nominal diameter of the sensor.
The optimum flow velocity is between 1 to 4 m/s (3.28 to 13.12 ft/s). The velocity of flow
(v), moreover, has to be matched to the physical properties of the fluid:

• v < 2 m/s (6.56 ft/s): For abrasive media such as cleaning agents etc.

• v > 2 m/s (6.56 ft/s): For media that produce buildup, such as oil and liquids that
contain sugar

A necessary increase in the flow velocity can be achieved by reducing the sensor
nominal diameter.

Flow characteristic values →  64

Flow limit The diameter of the pipe and the flow rate determine the nominal diameter of the sensor.

The optimum flow velocity is between 2 to 3 m/s (6.56 to 9.84 ft/s). Also match the
velocity of flow (v) to the physical properties of the fluid:

• v < 2 m/s (6.56 ft/s): For abrasive media (e.g. cleaning agents)

• v > 2 m/s (6.56 ft/s): For media that produce buildup (e.g. liquids containing oil and
sugar)

A necessary increase in the flow velocity can be achieved by reducing the sensor
nominal diameter.

Pressure loss • For DN 8 (5/16"), DN 15 (½") and DN 25 (1") no pressure loss occurs if the sensor is
