Description

5. DESCRIPTION

5.1. Area of application

The 8045 flowmeter is intended exclusively to measure flow rates in liquids.
The device makes it possible to switch a solenoid valve or activate an alarm thanks to a transistor output and, for some versions, by means of two relay outputs, fully configurable and to establish a control loop thanks to a 4-20 mA current output.
The versions also equipped with a digital input make it possible to remotely activate a function.

5.2. General description

The device comprises both a flow sensor operating on Faraday's law and a transmitter with display.
The device is equipped with a 4-20 mA current output (analogue output, called AO1), a digital output (configured as a pulse output by default, called DO1) and two totalisers.
Some versions are equipped with two relay outputs (called DO2 and DO3) and one digital input (called DI1).
The device operates on a 3 wire system and needs a 18-36 V DC power supply.
The electrical connection is made on the terminals blocks of the electronic board within the transmitter, through two M20 x 1,5 cable glands.

10 m 2 and 3 m/s.
• Solution: intersection between flow rate and flow velocity in the graph gives the appro­priate pipe diameter, DN40 (or DN50 for the asterisked fittings).
* For the fittings:
• with external thread connections acc. to SMS 1145,
• with welding end connections acc. to SMS 3008, BS 4825 / ASME BPE or DIN 11850 Rg 2,

7.3. 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.
note
The device is not tight if at least one cable gland is not used
• Seal the unused cable gland with the supplied stopper gasket:
→ Loosen the nut of the unused cable gland.
→ Remove the transparent disk.
→ Insert the supplied stopper gasket.
→ Screw the nut of the cable gland.
21
English
Type 8045
Installation and commissioning
• Use a high quality electrical power supply (filtered and regulated).
• Make sure the installation is equipotential. See chap. “7.3.1”.
• Use shielded cables with a temperature limit of 80 °C minimum.
• Do not install the cables near high voltage or high frequency cables; If this cannot be avoided, observe a min. distance of 30 cm.
• 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.
If two cables are used in the same cable gland, first insert the supplied multi-way seal.
To wire the device:
→ Loosen the screw from the lid.
→ Flip the lid.
→ Loosen the 4 screws from the cover of the housing.
→ Remove the cover.
→ Loosen the nuts of the cable glands.
→ Insert the cable through the nut then through the cable gland.
→ Make sure the earth cable coming from the housing and, on a version with stainless steel sensor, the cable
coming from the flow sensor, are connected as shown in Fig. 19, chap. 7.3.3.
→ Wire acc. to chap. 7.3.1 to 7.3.7.
7.3.1. Equipotentiality of the installation
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 connection cannot be made directly, a 100 nF/50 V capacitor can be fitted between the negative power supply terminal and the earth.
22
→ 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.

8.6.2. Choosing the flow rate units, the number of decimals and the units of the totalizers
When changing the flow rate unit, only the totalizers are automatically converted.
• If necessary, manually convert the parametered flow rate values.
The max. flow rate that can be displayed depends on the number of decimals chosen:
• 9999 if the number of decimals = 0 or AUTO,
• 999,9 if the number of decimals = 1,
• 99,99 if the number of decimals = 2,
• 9,999 if the number of decimals = 3.
The "UNIT" parameter makes it possible to choose:
• the flow rate units.
• a fixed number of decimals (choose 0, 1, 2 or 3) to display the flow rate in the Process level, or a floating
decimal point (choose "AUTO"): the device automatically adjusts the position of the decimal point depending on the chosen unit and the measured flow rate.

Make sure there are no bubbles in the pipe.
Before calibrating the flow zero point:
• at first commissioning the device, immerse the sensor in fluid for 24 hours before calibration.
• after maintenance work, immerse the sensor in the fluid for 1 hour before calibration.
During the calibration:
• the device status LED flashes.
• the outputs are frozen to the last measured flow rate value.
• the device cannot be configured.
The flow zero point calibration can be:
• either remotely triggered via the digital input. See chap. “8.6.12” and Fig. 56.
• either carried out using this parameter in the Test menu; See Fig. 57.
→ Charge the pipe.
→ Stop the fluid circulation.
