Type 8025 / 8035

Description

5. DESCRIPTION

5.1. Area of application

The compact version of the flowmeter type 8025 or 8035 is designed to measure the flow rate of a liquid and to totalise the volume of a liquid.

The remote version of the flowmeter type 8025 is a transmitter that must be connected to an 8020 or an 8030 flow sensor with a sinus or a pulse output, only in "Low Power" version.

5.2. General description

The 8025 is a flowmeter available in compact, panel or wall-mounted version. The 8035 is a flowmeter in compact version.

• A compact version of the 8025 is composed of a flow sensor with paddle-wheel and of an electronic module (the electronic is located in a housing with cover, display and 2 cable glands).

• A compact version of the 8035 is composed of a sensor-fitting type S030, with paddle-wheel and of an electronic module (the electronic is located in a housing with cover, display and 2 cable glands).

• A panel version of the 8025 is an electronic module (an electronic located in an open housing with display).

• A wall-mounted version of the 8025 is an electronic module (an electronic integrated in a housing with cover, display and 3 cable glands).

According to the version, the device requires a 12-36 V DC or a 115/230 V AC power supply. The electrical connection is carried out via a male fixed connector or on the terminal blocks of the electronic board: whether

directly, whether via 2 or 3 cable glands.

5.3. Measuring principle

The circulation of fluid within the pipe causes the paddle wheel of the sensor to rotate. The flowmeter detects the rotation of the paddle-wheel and generates a signal which frequency f is proportional to the flow rate Q, using the formula f = KxQ.

f = frequency in Hertz (Hz) K = K factor of the S020 or S030 fitting used, in pulse/litre Q = flow rate in litre/second

5.4. Available versions of the 8025 compact flowmeter

All the compact versions of the flowmeter 8025 have:

- a 4-20 mA current output;

- a pulse output ;

- two totalizers.

7.2. Installation of a compact version

7.2.1. Instructions for installing a compact version onto the pipe

The 8025 flowmeter has to be inserted into an S020 fitting mounted on a pipe. The 8035 flowmeter has to be installed on the pipe using the S030 sensor-fitting.

→ Choose an S020 or S030 fitting appropriate to the velocity of the fluid inside the pipe: refer to the graphs below:

Tab. 3: Flow rate/ fluid velocity/ DN of S020 fitting and of S030 sensor-fitting diagram

Flow rate

The device cannot be installed onto the following DN20 fittings:

* For the fittings:

• with external threads acc. to SMS 1145.

• with weld ends acc. to SMS 3008, BS 4825 / ASME BPE or DIN 11850 Rg2.

• Clamp acc. to SMS 3017 / ISO 2852, BS 4825 / ASME BPE or DIN 32676.

8. WIRING

DANGER

Risk of injury due to electrical voltage.

• Shut down the electrical power source of all the conductors and isolate it before carrying out work on the system.

• Observe all applicable accident protection and safety regulations for electrical equipment.

Insert the supplied stopper gaskets into the unused cable glands of a wall-mounted or a compact version to ensure the tightness of the device.

Only move the selectors when the power supply is off.

• Use a filtered and regulated 12-36 V DC power supply. The circuit has to be safety extra low voltage (SELV), with a safe energy level.

• Make sure the installation is equipotential. See chap. "8.1".

• Use shielded cables with an operating temperature limit of 80 °C minimum.

• Do not install the cables near high voltage or high frequency cables; if a combined installation cannot be avoided, a minimum space of 30 cm should be respected.

• Protect the power supply by means of a 300 mA fuse and a switch.

• Protect the relays by means of a max. 3 A fuse and a circuit breaker (depending on the process).

• Do not apply both a dangerous voltage and a safety extra-low voltage to the relays.

8.1. Making the installation equipotential

To ensure the equipotentiality of the installation (power supply - device - fluid):

→ Connect together the various earth spots in the installation to eliminate the potential differences that may occur between

different earthes.

→ Observe faultless earthing of the shield of the power supply cable, at both ends. → Connect the negative power supply terminal to the earth to suppress the effects of common mode currents. If this con-

nection cannot be made directly, a 100 nF/50 V capacitor can be fitted between the negative power supply terminal and the earth.

→ Special attention has to be paid if the device is installed on plastic pipes because there is no direct earthing possible.

Proper earthing is performed by earthing together the metallic instruments such as pumps or valves, that are as close as possible to the device. If no such instrument is near the device, insert metallic earth rings inside the plastic pipes upstream and downstream the device and connect these parts to the same earth. The earth rings must be in contact with the fluid.

• In particular, observe the safety recommendations and intended use.

• The device / the installation must only be commissioned by suitably trained staff.

• Before commissioning, set the K Factor of the fitting used. See chap. "9.6.3".

9.2. Operating levels of the device

The device has two operating levels: the Process level and the Configuration level. The Process level makes it possible:

• to read the flow rate measured by the device, the value of the current transmitted on the 4-20 mA analogue output, the values of both the daily and main totalizers;

• to reset the daily totalizer;

• to access the Configuration level.

The Configuration level has two menus (Parameters, Test) and makes it possible:

• to set the device parameters;

• to test some device settings.

• 999,9 if the number of decimals = 1.

• 99,99 if the number of decimals = 2.

• 999 999 if the volume unit chosen is "m

• When the flow rate unit is changed convert the flow rate values set within the "CURRENT", "PULSE" and "RELAYS" parameters of the Parameters menu.

The "UNIT" parameter makes it possible to choose:

• the flow rate units;

• a fixed number of decimals (choice 0, 1, 2 or 3) to display the flow rate in the Process level;

• the volume units of the totalizers if the unit previously chosen is in litres, in m

The device determines the flow rate in the pipe using the fitting K factor. The K factor of the fitting used can be entered here. The device may also determine the K factor using a teach-in procedure:

see "Fig. 58".
