However, the device should not, under any circumstances, be mounted less than 20 cm/ 8“ from the vessel wall. • Not in the centre (3), interference can cause signal loss. • Not above the fill stream (4). • It is recommended to use a weather protection cover (2) in order to protect the transmitter from direct sun or rain.
Installation Micropilot M FMR250 with HART/4...20 mA Beam angle The beam angle is defined as the angle a where the energy density of the radar waves reaches half the value of the maximum energy density (3dB-width). Microwaves are also emitted outside the signal beam and can be reflected off interfering installations.
Micropilot M FMR250 with HART/4...20 mA Installation Measuring conditions • The measuring range begins, where the beam hits the vessel bottom. Particularly with dish bottoms or conical outlets the level cannot be detected below this point. • In case of media with a low dielectric constant (groups A and B), the vessel bottom can be visible through the medium at low levels. In order to guarantee the required accuracy in these cases, it is recommended to position the zero-point at a distance C =50...
Installation Micropilot M FMR250 with HART/4...20 mA Measuring range The usable measuring range depends on the size of the antenna, the reflectivity of the medium, the mounting location and eventual interference reflections. The maximum configurable range is 70 m (229 ft) for Micropilot M FMR250.

Micropilot M FMR250 with HART/4...20 mA 5.3.3 " Operation Factory settings (Reset) Caution! A reset sets the instrument back to the factory settings. This can lead to an impairment of the measurement. Generally, you should perform a basic setup again following a reset.
Operation Micropilot M FMR250 with HART/4...20 mA 5.4 Display and acknowledging error messages Type of error Errors that occur during commissioning or measuring are displayed immediately on the local display. If two or more system or process errors occur, the error with the highest priority is the one shown on the display. The measuring system distinguishes between two types of error: • A (Alarm): Instrument goes into a defined state (e.g. MAX 22 mA) Indicated by a constant symbol.
Micropilot M FMR250 with HART/4...20 mA 5.5 Operation HART communication Apart from local operation, you can also parameterise the measuring instrument and view measured values by means of a HART protocol. There are two options available for operation: • Operation via the universal handheld operating unit, the HART Communicator DXR375. • Operation via the Personal Computer (PC) using the operating program (e.g. ToF Tool or Commuwin II) (For connections, see Page 29).

Micropilot M FMR250 with HART/4...20 mA Commissioning Function "full calibr." (006) ENDRESS + HAUSER – + E ⇒ This function is used to enter the distance from the minimum level to the maximum level (=span). L00-FMR2xxxx-14-00-06-en-009 In principle, it is possible to measure up to the tip of the antenna. However, due to considerations regarding corrosion and build-up, the end of the measuring range should not be chosen any closer than 50 mm (2") to the tip of the antenna.
Commissioning Micropilot M FMR250 with HART/4...20 mA Function "pipe diameter" (007) ENDRESS + HAUSER – + E ⇒ This function is used to enter the pipe diameter of the stilling well or bypass pipe. L00-FMR2xxxx-14-00-00-en-011 Microwaves propagate more slowly in pipes than in free space. This effect depends on the inside diameter of the pipe and is automatically taken into account by the Micropilot. It is only necessary to enter the pipe diameter for applications in a bypass or stilling well.
Micropilot M FMR250 with HART/4...20 mA Commissioning Function "check distance" (051) ENDRESS + HAUSER – + E ⇒ This function triggers the mapping of interference echoes.

Micropilot M FMR250 with HART/4...20 mA 9.7 Trouble-shooting Return The following procedures must be carried out before a transmitter is sent to Endress+Hauser e.g. for repair or calibration: • Remove all residue which may be present. Pay special attention to the gasket grooves and crevices where fluid may be present. This is especially important if the fluid is dangerous to health, e.g. corrosive, poisonous, carcinogenic, radioactive, etc.
Technical data Measured variable Micropilot M FMR250 with HART/4...20 mA 10 Technical data 10.1 Additional technical data 10.1.1 Input The measured variable is the distance between a reference point and a reflective surface (i.e. medium surface). The level is calculated based on the tank height entered. The level can be converted into other units (volume, mass) by means of a linearization. 10.1.

Micropilot M FMR250 with HART/4...20 mA Appendix 11.3 Function and system design 11.3.1 Function (Measuring principle) The Micropilot is a "downward-looking" measuring system, operating based on the time-of-flight method. It measures the distance from the reference point (process connection) to the product surface. Radar impulses are emitted by an antenna, reflected off the product surface and received again by the radar system.
Appendix Micropilot M FMR250 with HART/4...20 mA Output The Micropilot is commissioned by entering an empty distance E (=zero), a full distance F (=span) and an application parameter. The application parameter automatically adapts the instrument to the process cond.. The data points “E” and “F” correspond with 4mA and 20mA for instruments with current output. They correspond with 0 % and 100 % for digital outputs and the display module. A linearization with max.
Micropilot M FMR250 with HART/4...20 mA Appendix On-site operation • with display and operating module VU331, • with a Personal Computer, FXA193 and the operating software "ToF Tool - FieldTool Package" respectively "FieldCare". The ToF Tool is a graphical operating software for instruments from Endress+Hauser that operate based on the time-of-flight principle (radar, ultrasonic, guided micro-impulse). It assists with commissioning, securing data, signal analysis and documentation of the measuring point.
