3 INSTALLATION OPTIWAVE 7400-24 C Figure 3-7: General Installation recommendations 1 Do not tilt the device more than 2° 2 We recommend that you do an empty spectrum recording if there are too many obstacles in the radar beam (for more data, refer to How to make a filter to remove radar signal interference on page 75). If necessary, install a bypass chamber or stilling well or use an "L" antenna extension (the device must be installed on the side of the tank) to move the device away from obstacles. 3 2.
INSTALLATION 3 OPTIWAVE 7400-24 C CAUTION! Do not put the device near to the product inlet. If the product that enters the tank touches the antenna, the device will measure incorrectly. If the product fills the tank directly below the antenna, the device will also measure incorrectly. Figure 3-9: Product inlets 1 The device is in the correct position. 2 The device is too near to the product inlet. 3.7.3 Devices with Metallic Horn antenna The antenna must project out of the nozzle.
3 INSTALLATION OPTIWAVE 7400-24 C • • • • • Make sure the flange on the nozzle is level. Make sure that you use the applicable gasket for the flange dimensions and the process. Align the gasket correctly on the flange facing of the nozzle. Lower the antenna carefully into the tank. Make sure that you point the device in the correct direction. Refer to "Point the device in the correct direction" in this section. • Tighten the flange bolts.
INSTALLATION 3 OPTIWAVE 7400-24 C 3.7.5 Standpipes (stilling wells and bypass chambers) Use a standpipe if: • • • • • There is highly conductive foam in the tank. The liquid is very turbulent or agitated. There are too many other objects in the tank. The device is measuring a liquid (petro-chemicals) in a tank with a floating roof.
3 INSTALLATION OPTIWAVE 7400-24 C • Drill 1 or more liquid circulation holes in the stilling well (if there is more than 1 liquid in the tank). i These holes help the liquid to move freely between the stilling well and the tank. • Remove the burr from the hole. Stilling wells: floating roofs If the device must be installed on a tank with a floating roof, install it in a stilling well.

OPERATION 6 OPTIWAVE 7400-24 C 6.4.8 How to make a filter to remove radar signal interference If the device measures level in a tank that contains obstructions (agitator, supports, heating pipes etc.), these objects can cause radar signal interference (parasitic signals). You can use the empty spectrum function (menu item 2.1.2) in the Quick Setup menu to make a filter to remove radar signal interference.
6 OPERATION OPTIWAVE 7400-24 C • Subtract the distance to the reflection from the true tank height. • Go to Supervisor > Advanced Setup > Installation Setup > Tank Bottom Offset Offset. • Type in the difference you calculated as a negative value. i A negative value will move the reference point above the tank bottom (as given in menu item C.1.2 Tank height). • Push [^ ^]. • Push [> >] and [ ] (Esc) at the same time to exit to the "save settings" window. • Select Save and push [^ ^].

TECHNICAL DATA 8 OPTIWAVE 7400-24 C 8.1 Measuring principle A radar signal is emitted via an antenna, reflected from the product surface and received after a time t. The radar principle used is FMCW (Frequency Modulated Continuous Wave). The FMCW-radar transmits a high frequency signal whose frequency increases linearly during the measurement phase (called the frequency sweep). The signal is emitted, reflected on the measuring surface and received with a time delay, t.

9 DESCRIPTION OF HART INTERFACE OPTIWAVE 7400-24 C 9.1 General description The HART® Protocol is an open digital communication protocol for industry. It is free to use by anyone. It is included in the software embedded in signal converters of HART-compatible devices. There are 2 classes of devices which support the HART® Protocol: operating devices and field devices. There are 2 classes of operating devices (Master): PC-supported workstations (Primary Master) and manual control units (Secondary Master).
OPTIWAVE 7400-24 C DESCRIPTION OF HART INTERFACE 9 9.3 Connection variants The signal converter is a 2-wire device with 4...20 mA current output and HART® interface. • Multi-Drop Mode is supported In a Multi-Drop communication system, more than 1 device is connected to a common transmission cable. • Burst Mode is not supported There are two ways of using the HART® communication: • as Point-to-Point connection and • as Multi-Drop connection with 2-wire connection. 9.3.
