INSTALLATION 3 TIDALFLUX 2300 F 3.1 General notes on installation INFORMATION! Inspect the cartons carefully for damages or signs of rough handling. Report damage to the carrier and to the local office of the manufacturer. INFORMATION! Do a check of the packing list to make sure that you have all the elements given in the order. INFORMATION! Look at the device nameplate to ensure that the device is delivered according to your order. Check for the correct supply voltage printed on the nameplate. 3.
3 INSTALLATION TIDALFLUX 2300 F 3.5 General requirements INFORMATION! The following precautions must be taken to ensure reliable installation. • Make sure that there is adequate space to the sides. • Protect the signal converter from direct sunlight and install a sun shade if necessary. • Signal converters installed in control cabinets require adequate cooling, e.g. by fan or heat exchanger. • Do not expose the signal converter to intense vibration.
INSTALLATION 3 TIDALFLUX 2300 F 3.6 Installation conditions 3.6.1 Inlet and outlet Figure 3-4: Recommended inlet and outlet sections, top view 1 ≥ 5 DN 2 ≥ 3 DN 3.6.2 Control valve Figure 3-5: Installation before control valve 3.6.3 Slope CAUTION! The accuracy is influenced by the slope. Stay within ±1% to get the most accurate measurements! Figure 3-6: Recommended slope 06/2013 - 4002490202 MA TIDALFLUX 2300 F R02 en www.krohne.
3 INSTALLATION TIDALFLUX 2300 F 3.6.4 Mounting advice for difficult situations If you can not meet the installation conditions install the flowmeter between two containers. The inlet to the flowmeter must be higher than the outlet of the fluid. In this way you will have a calm flow into the flowmeter, resulting in a highly accurate measurement. The sizes of the containers must be proportional to the size of the flowmeter.
INSTALLATION 3 TIDALFLUX 2300 F 3.6.6 Cleaning of flow sensor The flow sensor is highly resistant against dirt and the measurement will rarely be influenced by anything. However, it is advisable to create a possiblity for cleaning just in front or behind the sensor. Figure 3-9: Option for cleaning of flow sensor 1 Opening for cleaning 3.6.7 Flange deviation CAUTION! Max. permissible deviation of pipe flange faces: Lmax - Lmin ≤ 0.5 mm / 0.02" Figure 3-10: Flange deviation 1 Lmax 2 Lmin 3.6.

TECHNICAL DATA 6 TIDALFLUX 2300 F 6.1 Measuring principle The TIDALFLUX 2000 is an electromagnetic flow sensor with an integrated capacitive level measurement system, designed for electrically conductive process liquids. The flow rate Q(t) through the tube is: Q(t) = v(t) x A(t), A(t) in which v(t) = flow velocity of liquid product A(t) = wetted area of tube section. The flow velocity is determined on basis of the known electromagnetic measurement principle.

Arrow on flow sensor indicates positive flow direction.

TECHNICAL DATA 6 TIDALFLUX 2300 F Electrical connections General Electrical connection is carried out in conformity with the VDE 0100 directive "Regulations for electrical power installations with line voltages up to 1000 V" or equivalent national specifications. Power supply Standard: 100...230 VAC (-15% / +10%), 50/60 Hz Option 1: 24 VAC/DC (AC: -15% / +10%, 50/60 Hz; DC: -25% / +30%) Power consumption AC: 22 VA Field current cable Shielded cable must be used, no part of delivery.
6 TECHNICAL DATA TIDALFLUX 2300 F 6.3 Sizing INFORMATION! These tables state the flowrate in a partially filled pipe, dependant on slope, filling level, inner diameter and friction factors of the pipe. The values are calculated according the ManningStrickler equation. The results do not consider: deposits, profile distortion, backwater, friction of air and the slightly smaller inner diameter of the TIDALFLUX.
TECHNICAL DATA 6 TIDALFLUX 2300 F Figure 6-2: Relative flow and velocity versus relative filling level 1 Flow Q 2 Velocity v INFORMATION! vmax and Qmax are the values of v and Q if the pipe is completely filled EXAMPLE: Consider a maximum flow to be measured of 1200 m3/h. The material of the pipeline is steel and the slope 1.0%. From the table a maximum flow has to be selected that is bigger than the flow to be measured. Selection: DN500, Qmax = 1767 m3/h and vmax = 2.5 m/s.
6 TECHNICAL DATA TIDALFLUX 2300 F 6.4 Dimensions and weights The inner pipe diameter should match the inner diameter of the flowmeter. Since the inner diameter is not a standard DN size, choose the inner pipe diameter to be just a little bit bigger than the flowmeter diameter. If a lot of sediment or fat is expected the optimal solution is to produce a diameter compensation ring on both sides to have smooth transits. k = 230 mm / 89.1" m = 265 mm / 10.4" n = 251 mm / 9.

6 TECHNICAL DATA TIDALFLUX 2300 F 6.5 Measuring accuracy The measuring accuracy for partly filled pipes and completely filled pipes are different. In these graphs it is assumed that the velocity at full scale value is at least 1 m/s (is also the standard value for calibration, since it will result in the most accurate measurements). Partly filled: • v @ Full Scale ≥ 1 m/s / 3.3 ft/s: ≤ 1% of Full Scale Fully filled: • v ≥ 1 m/s / 3.3 ft/s: ≤ 1% of MV • v < 1 m/s / 3.3 ft/s: ≤ 0.5% of MV + 5 mm/s / 0.
