3 INSTALLATION
3.4 Installation conditions
CAUTION!
When installing the device in the piping, the following points must be observed:
•
The variable area flowmeter must be installed vertically (measuring principle). Flow direction
from bottom to top. For installation recommendations please refer also to directive VDI/VDE
3513, sheet 3.
•
A straight unimpeded inlet run of ≥ 5x DN upstream of the device and a straight outlet run of
≥ 3x DN downstream of the device are recommended.
•
Screws, bolts and gaskets are to be provided by the customer and must be selected in
accordance with the pressure rating of the connection or the operating pressure.
•
The inside diameter of the flange deviates from the standard dimensions. Flange seal
standard DIN 2690 can be applied without any limitation.
•
Align the gaskets. Tighten the nuts with the tightening torques of the appropriate pressure
rating.
For devices with PTFE liner or ceramic liner and PTFE raised faces, refer to chapter
"Tightening torques".
•
Control devices are to be positioned downstream of the measuring device.
•
Shutoff devices are preferably to be positioned upstream of the measuring device.
•
Before connecting, blow or flush out the pipes leading to the device.
•
Pipes for gas flow need to be dried before the device is installed.
•
Use connectors suitable for the particular device version.
•
Align the pipes centrically with the connection bores on the measuring device so they are free
of stresses.
•
If necessary, the piping has to be supported to reduce the vibrations transmitted to the
measuring device.
•
Do not lay signal cables directly next to cables for the power supply.
H250
3.4.1 Magnetic filters
The use of magnetic filters is recommended when the medium contains particles which can be
influenced magnetically. The magnetic filter is to be installed in the flow direction upstream of
the flowmeter. Bar magnets are positioned helically in the filter to provide optimal efficiency at
low pressure loss. All of the magnets are coated individually with PTFE to protect against
corrosion. Material: 1.4571
Magnetic filters

ELECTRICAL CONNECTIONS 4
Wiring must be planned with great care when it comes to connecting other devices such as
evaluation units or process control. Internal connections in these devices (e.g. GND with PE,
mass loops) may lead to non-permitted voltage potentials which could negatively affect the
function of the converter itself or that of a device connected to it. In such cases a protected extralow voltage (PELV) is recommended.

Power supply
INFORMATION!
The supply voltage has to be between 12 VDC and 30 VDC. This is based on the total resistance of
the measuring loop. To calculate this, the resistance of each component in the measuring loop
(not including the device) must be added together).
The required supply voltage can be calculated using the formula below:
.
= R

where
U

= the total measuring loop resistance.

The power supply has to be able to supply a minimum of 22 mA.

H250
Current output adjustment
A fine adjustment of the current output can be performed using the ZERO and SPAN
adjustment screws of the KINAX 3W2 angular position transmitter.
For adjustment of 4.00 mA, the pointer must be set to RP on the scale. 4.00 mA can be set
using ZERO.
For adjustment of 20.00 mA, the pointer must be set to 100% flow rate value of the scale. 20.00
mA can be set using SPAN.
Instead of manual adjustment of the pointer, the flow rate values ??0 and 100% can be set for
the adjustment.

4.3 Ground wire
DANGER!
The grounding wire may not transfer any interference voltage.
Do not use this grounding cable to ground any other electrical devices.
4.4 Ingress protection
ELECTRICAL CONNECTIONS 4
The measuring device meets all requirements of protection category IP66/67.
DANGER!
After all servicing and maintenance work on the measuring device, the specified protection class
must be ensured again.
Therefore it is essential to observe the following points:
• Use only original gaskets. They must be clean and free of any damage. Defective gaskets must
be replaced.
• The electrical cables used must be undamaged and must comply with regulations.
• The cables must be laid with a loop 3333 upstream of the measuring device to prevent water
from getting into the housing.
• The cable feedthroughs 2222 must be tightened.
• Close the unused cable feedthroughs using blind plugs 1111.

5 START-UP
5.1 Standard device
CAUTION!
When starting up the device, the following points must be observed:
•
Compare the actual operating pressure and the product temperature of the system with the
specifications on the nameplate (PS and TS). These specifications may not be exceeded.
•
Make sure materials are compatible.
•
Slowly open the shut-off valve.
•
When measuring liquids, vent the pipes carefully.
•
When measuring gases, increase pressure slowly.
•
Avoid float impact (e.g. caused by solenoid valves), as this is likely to damage the measuring
unit or float.
A minimum operating pressure (primary pressure) is necessary to operate the device:
Medium Pressure loss : operating pressure
H250
Liquids 1 : 2
Gases without float damping 1 : 5
Gases with float damping 1 : 2

H250
6.1 Maintenance
Within the scope of routine maintenance of the system and pipelines, the flowmeter should also
be inspected for signs of fouling, corrosion, mechanical wear and leaks, as well as damage to
the measuring tube and indicator.
We advise that inspections be carried out at least once per year.
The device must be removed from the piping before cleaning.
CAUTION!
Pressurized pipes must be depressurized before removing the device.
Empty pipes as completely as possible.
In the case of devices used for measuring aggressive or hazardous media, appropriate safety
precautions must be taken with regard to residual liquids in the measuring unit.
Always use new gaskets when reinstalling the device in the pipeline.
Avoid electrostatic charges when cleaning the surfaces (e.g. sight window)!
6.2 Replacement and retrofitting
SERVICE 6
Some components of the variable area flowmeter can be exchanged or retrofitted:
• Float
• Float damping
6.2.1 Replacing floats
• Remove the device from the piping.
• Take the upper snap ring out of the measuring unit.
• Take the upper float stop and float out of the measuring unit.
• Insert the new float into the centre hole of the lower float stop and push into the measuring
unit along with the upper float catcher. While doing this, the float's upper guide rod must be
guided through the middle hole of the float stop.
• Insert the snap ring into the measuring unit.
• Fit the device back into the piping.
CAUTION!
An additional measuring error is to be expected if recalibration is not conducted.

7.1 Functional principle
The H250 flowmeter operates on the float measuring principle. The measuring unit consists of a
metal cone in which a float can move freely up and down. The flow goes from bottom to top. The
float changes position so that the lifting force acting on it A is in equilibrium with the form drag W
and its weight G: G = A + W.
