2 DEVICE DESCRIPTION

2.2.1 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 (see 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:

DN 100 4" ≤0.2 ≤2.9

H250

2.2.2 Pointer damping

The pointer system with its magnetic system basically contains pointer damping. An additional eddy current brake is advantageous for fluctuating or pulsing flows. The eddy current brake magnets surround the pointer vane 1 without touching it, damping its movement. The result is a pointer position that is considerably calmer, and no distortion of the measured value. A clamp screw holds it in place securely. The eddy current brake can be retrofitted without having to recalibrate and while in operation (see Service).

Power supply M8 with electrical isolation

The circuitry for connection to other devices such as digital evaluator units or process control equipment must be designed with especial care. In some circumstances internal connections in these devices (e.g. GND with PE, ground loops) may lead to impermissible voltage potentials, which can compromise the function of the device itself or a connected device. In such cases a protected extra-low voltage (PELV) is recommended.

4.3.4 Indicator M9 - totalizer (ESK-Z)

The totalizer only works in conjunction with the ESK2A current output. A 6-digit display shows the totalised flow value. It can be changed over to the instantaneous flow value in 0...100%.

A data backup is carried out automatically in the event of a power failure.

The counter is factory-set to the measuring range of the indicator. The total value can be read directly.

Supply 11/12 and measured signals S+ and S- are not electrically isolated. If the measured signal is not needed externally, a short-circuit jumper has to be connected to terminals S+ and S-.

Pulse outputs P+ and P- are electrically isolated. A pulse is generated for each counter advance. If the pulse output is not required, its terminals can remain unused.

With variable area flowmeters, the flow range from 0 to 10% is not defined. In order to ensure a stable zero point of the analogue output, the analogue output can be set to a stable value of 4.00mA in a selectable range from 0 to 20%.

The flow is greater than 20%. The current output corresponds to this. If the flow rate falls, then the current output follows it until the ON value. If the flow value continues to fall, the current output is switched to

4.00 mA 3.

The flow rate is 0. The current output is 4.00 mA 3. If the flow rate rises, the current output remains at 4.00 mA 3 until the OFF value, and is switched to the corresponding flow value if the flow value rises further.

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 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)!

8 TECHNICAL DATA

8.1 Operating principle

The flowmeter H250 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 medium flows through the flowmeter from bottom to top. The float adjusts itself so that the buoyancy force B, acting on it, the form drag D and its weight W are in equilibrium: W = B + D.

Figure 8-1: Operating principle

1 Indication principle M9 and M8MG 2 Indication principle M10 and M8EG

H250

For indicators M9 and M8MG 1 the flow-dependent height of the float in the measuring unit is transmitted by means of a magnetic coupling and displayed on a scale. For indicators M10 and M8EG 2 the flow-dependent height of the float in the measuring unit is transmitted to the electronic display by magnetic field sensors S1 and S2.

Operating principle of H250H and H250U

Figure 8-2: Operating principle H250H and H250U

1 H250H - horizontal flow direction 2 H250U - flow direction from top to bottom

The flowmeters operate according to 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.

INFORMATION!

Flowmeters H250H and H250U only work in conjunction with indicator M9.
