Failure to install this filter can cause major damage to the equipment. This filter must be installed following the minimum flow meter inlet length indications to maintain laminar flow. · The indications described in the user manual must be followed. ELECTRICAL INSTALLATION. Only for models with power supply with pulse output. · The power supply supplying voltage to the flowmeter: o It must not exceed 30 Vdc or be less than 12 Vdc. o It must not supply INDUCTIVE LOADS (Coils, solenoid valves, contactors, etc.). · The polarity of the power supply cannot be reversed. · The pulse output does not support loads greater than 100 mA. · Power cables (Greater than 110 Vac) and Data (Pulse, analog, etc.) must go through separate conduits. These turbine flowmeters have a magnetic pulse sensor to collect the rotation of each blade of the propeller inside the measuring tube. If the flowmeter has a strong electromagnetic field nearby that comes from an electric motor or other element such as a transformer, the pulse pickup may be influenced by this electromagnetic field. The pulse cable must go through signal channeling, never power and this must be shielded with one end of this mesh to ground. Nor can the excess cable be wound making a coil. The fluid cannot carry air, since the flow meter would measure this air and the liquid. ii 1. General information Manual de operación Turbinas 1.1. Measuring principle Turbine flowmeters are equipped with a propeller that rotates when the flow circulates inside it. The rotation speed is proportional to the flow rate, so once the speed is known, the flow rate can be determined. To know this, a sensor is used that generates a pulse every time a propeller blade passes in front of it. In this way, a train of pulses is obtained whose frequency allows the flow rate to be determined. 3 2. Equipment Description Turbine Flowmeter User Manual 2.1.

Transmitters Transmitters are electronic devices that are used to calculate, using the pulses/liter factor, the volume of liquid that passes through the Turbine flowmeter. Depending on the model chosen, there is the option of having local indication (display), pulse output, analog output, or all combined. CEB01C CEB01MA CEB09 (BV/BVSI/BVSIA) - CEB01C: NPN PNP transistor output, without local indication. - CEB01MA: Analog (4 20 mA) output, without local indication. - CEB09BV: Local Indication of: o Total Volume: Total liters that have passed through the equipment since the beginning of its operation, with a resolution of 8 digits. o Partial Volume: Total liters that have passed through the equipment since the last reset, with a resolution of 7 digits. o Volumetric Flow: Instantaneous flow rate that circulates through the flowmeter, with a resolution of 5 digits. - CEB09BVSI: Local indication and NPN PNP transistor output. - CEB09BVSIA: Local indication, NPN PNP transistor and analog (4 20 mA) output.

Installation Turbine Flowmeter User Manual 3.1. Mechanical installation Stainless steel turbine flowmeters accurately measure when correct mechanical installation is performed. The recommendations that are exposed in this section, try to achieve the following objectives: · Laminar flow: The liquid that passes through the equipment must do so in a laminar regime, that is, not turbulent. · Always with liquid: The flowmeter must always be filled with liquid. · Avoid the passage of air: The passage of air, or other gas through the flowmeter must be avoided. Caution: A 0.5 1 mm (0.02 0.04 in) mesh FILTER must be installed in front of the flowmeter to protect it. Failure to install this filter can cause major damage to the equipment. This filter must be installed following the minimum flow meter inlet length indications to maintain laminar flow. 3.1.1. Laminar Flow Straight sections. It is essential to place a section of straight pipe with the same internal diameter as that of the flow meter and, as a general rule, with a minimum length of 5 times the diameter at the outlet and 10 times the diameter at the inlet. Reductions. If the diameter of the pipe is different from that of the flowmeter, concentric reductions must be placed before and after the indicated straight sections. Curved sections. In front of or behind these straight tubes other elements or curved sections can be placed. 8 Turbine Flowmeter User Manual Valves. Manual valves must be placed behind the flow meter. If you want to put them in front of it, you have to increase the straight section to 30 D. This is because, if a valve is left half open, the laminar flow of the liquid is greatly altered. Unions with the pipe. The unions of the flowmeter with the pipes are critical points where turbulence can occur, affecting the precision of the equipment, if they are not carried out properly. · As already indicated, the internal diameter of the pipe must be equal to that of the flow meter. · Furthermore, the union fitting and gasket must not disturb the flow of the liquid. This point may be particularly important in the case of flanged junction TB turbine flowmeters. Gasket 1 - Inner diameter of gasket and flange 2 - Internal diameter of flowmeter 3 - Internal diameter of the pipe It is very important that the gasket is centered and that it has the same internal diameter to avoid turbulence at the inlet of the flowmeter. It is recommended to use self-centering gaskets such as: · Gaskets whose outside diameter rests on the inside of the bolts. · Gaskets with dimensions equal to the flanges, including their holes. 9 Turbine Flowmeter User Manual 3.1.2. Always with liquid The flow meter can be mounted in the pipeline in a VERTICAL or HORIZONTAL POSITION, but it must always be avoided that the flow meter can remain empty. A flowmeter should never be installed in an open discharge. 3.1.3. Avoid air passage The passage of air or any gas through the flowmeter must be avoided, otherwise a measurement error would be made. If it cannot be avoided, a degasser or any other system must be installed that prevents air from passing through the equipment. In mobile installations, the air hose must be purged before reaching the flow meter. Important. The passage of compressed air, steam or any other gas under pressure can seriously damage the turbine flow meter. 3.1.4. Other recommendations The flow meter must not be mounted next to the electric motor of a pump. It must be moved a minimum of 50 cm away. The fluid should not back up, otherwise it would count it positively. If there is a risk that this circumstance could occur, a non-return valve must be fitted. In lines with very hot liquids, if the flowmeter is installed in a horizontal line, rotate it 90 degrees so that the transmitter is not above the pipe, as the internal electronics could overheat. 10 4.
