2.2.2 Float damping
Float damping is characterised by high standstill times and self-centering. The damping sleeve is made of high performance ceramic or PEEK, depending on the medium and the application. Float damping can also be retrofitted for the user (refer to "Service").
Use of damping
Generally when CIV and DIV floats are used for gas measurement.
For TIV floats (H250/RR and H250/HC only) with an operating primary pressure:
EN 1092-1 ASME B16.5 [bar] [psig]
DN50 1/2" 0.3 4.4 DN25 1" 0.3 4.4 DN50 2" 0.2 2.9 DN80 3" 0.2 2.9
DN100 4" 0.2 2.9
DEVICE DESCRIPTION
Nominal size according to Operating primary pressure
2
2.2.3 Pointer damping
In principle, the indicating element with its magnetic system contains indicator damping. An additional eddy current brake is advantageous in the event of fluctuating or pulsing flows. The magnets on the eddy current brake surround the pointer vane without touching it, damping its movement. The result is a much steadier pointer position, without distorting the measured value. The eddy current brake can be retrofitted during operation without recalibration. Note the maximum tightening torque (0.12 Nm) for the turnbuckle!
Figure 2-7: Pointer damping
1 Eddy current brake 2 Pointer vane 3 Support 4 Pointer cylinder 5 Turnbuckle, max. tightening torque is 0.12 Nm

INSTALLATION
3.3 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.
H250Hs are installed horizontally and H250U devices are installed vertically with the flow direction from top to bottom.
A straight unimpeded inlet run of 5 DN upstream of the device and a straight outlet run of 3 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 inner diameter of the flange deviates from the standard dimensions. Flange seal standard DIN 2690 or ASME B16.21 can be applied.
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.
Piping for gas flow need to be dried before the device is installed.
Use connectors suitable for the particular device version.
Align the piping 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.

Power supply M40 with galvanic isolation
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.

One of the following functions can be selected as contact type in Fct. 3.3: NORM.OPEN 1 / NORM.CLOSED 2
Value range: 0.0full scale range The switching point is entered in flow units. If the current flow value exceeds this pre-determined switching point, output B1 changes its binary state 3.

In Fct. 1.1.2 a hysteresis can be specified additionally.
CNT. VAL. B1 Switching point of totaliser value
PULSE WIDTH Pulse weight (pulse/unit)
1.1.2 HYST. B1 Hysteresis for the switching point of the flow value
Value range: 0.0counter limit The switching point is entered in volume or mass units. If the the current counter value exceeds this pre-determined switching point, output B1 changes its binary state 3. There is no hysteresis setting for the switching point of the counter value.
The weight is only displayed here.
A configuration takes place in Fct. 1.3.1 PULSE WIDTH, 1.3.2 PULSE/UNIT and 3.11.2 COUNTER.
Value range: 0.0switching point If the current flow value exceeds the pre-determined switching point from Fct. 1.1.1, output B1 changes its binary state 3. In order for output B1 to change its binary state back to the initial setting, the switching point made smaller by the hysteresis must be undershot 4.
Example:
Example:
Example:Example: In 1.1.1, a switching point of 200 L/h is set. The possible value range for the hysteresis is then 0.0…200 L/h. With a hysteresis value of 0, the switching point has no hysteresis (3=4). If a hysteresis value of 20 L/h is entered, output B1 changes its binary state to the initial setting, if it drops below 180 L/h 4.

7.1 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 the indicator. We advise that inspections are carried out at least once per year. The device must be removed from the pipeline before cleaning.
CAUTION!
Pressurised pipes have to be depressurised before removing the device. Empty the pipelines 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. New gaskets have to be used when re-installing the device in the pipeline. Avoid electrostatic charges when cleaning the surfaces (e.g. sight window)!

7.2.1 Replacing floats
Remove the device from the pipeline.
Take the upper span 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 stop. While doing this, the float's upper guide rod must be guided through the middle hole of the float stop.
Insert the span ring into the measuring unit.
Fit the device back into the pipeline.
CAUTION!
Without a recalibration an additional measuring error is to be expected.

7.2.4 Replacement - Retrofitting ESK4 / ESK4A
CAUTION!
When replacing or retrofitting an ESK4 / ESK4A, it is mandatory to indicate the serial number (SN) or sales order (SO) when ordering. This information can be found on the indicator nameplate.
The ESK4 / ESK4A is factory calibrated, making it possible to replace it or retrofit it without recalibrating.
De-energise the ESK4 / ESK4A.
Lift and remove the ESK4 / ESK4A with a screwdriver.
WARNING!

The ESK4 / ESK4A plug-in tongues 1 are plugged in under the two bolts 2 on the base plate.
Slight pressure is used to press the ESK4 / ESK4A onto the spring pins 3 until it stops, firmly
attaching the ESK4 / ESK4A.
If a change in measuring range, product temperature, product, density, viscosity or pressure is desired, this can be done with the help of a variable area calculation program and with a HART
modem. However, each measuring unit is subject to its own physical limits, which the variable area calculation program correctly calculates, and may thus reject the desired change. If a change is performed using the program, the new data is also transmitted to the ESK4 / ESK4A:

TECHNICAL DATA
8.1 Functional principle
The H250 flowmeter operates in accordance with the float measuring principle. The measuring unit consists of a metal cone in which a float can move freely up and down. The medium flows through the flowmeter from bottom to top. The float adjusts itself so that the buoyancy force F1 acting on it, the form resistance F2 and its weight F3 are in equilibrium: F3 = F1 + F2
H250 M40
Figure 8-1: Measuring principle - general
1 Indication principle M40 magnetic coupling 2 Magnetic coupling sensors
1 For the indicator, the flow-dependent height of the float in the measuring unit is transmitted
by means of a magnetic coupling and displayed on a scale.
2 For a built-in signal converter (ESK4 / ESK4A), the flow-dependent height of the float in the measuring unit is detected by the S1 and S2 magnetic field sensors and electronically processed.

The flowmeter operates in accordance with a modified float measuring principle. The guided float adjusts itself so that the flow force acting on it is in equilibrium with the opposing spring force. The flow-dependent position of the float in the measuring unit is displayed on a scale by means of a magnetic coupling.
