		Micropilot FMR51, FMR52
	Function and system design
Measuring principle	The Micropilot is a "downward-looking" measuring system, operating based on the time-of-flight
	method (ToF). 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.

1 Setup parameters of the Micropilot

R Reference point of the measurement (lower edge of the flange or threaded connection) E Empty calibration ( = zero)

F Full calibration (= span) D Measured distance

LLevel (L = E - D)

Input

The reflected radar impulses are received by the antenna and transmitted into the electronics. A microprocessor evaluates the signal and identifies the level echo caused by the reflection of the radar impulse at the product surface. The unambiguous signal identification is accomplished by the PulseMaster® eXact software together with the Multi-echo tracking algorithms, based on many years of experience with time-of-flight technology.

The distance D to the product surface is proportional to the time of flight t of the impulse: D = c · t/2,

with c being the speed of light.

Based on the known empty distance E, the level L is calculated: L = E – D

The reference point R of the measurement is located at the process connection. For details see the dimensional drawing:

•FMR51: → 67

•FMR52: → 73

The Micropilot is equipped with functions to suppress interference echoes. The user can activate these functions. Together with the multi-echo tracking algorithms they ensure that interference echoes (i.e. from edges and weld seams) are not interpreted as level echo.

Micropilot FMR51, FMR52

Output

The Micropilot is commissioned by entering an empty distance "E" (=zero), a full distance "F" (=span) and application parameters which automatically adapt the instrument to the process conditions. For models with a current output, the factory adjustment for zero point "E" and span "F" is 4 mA and 20 mA. For digital outputs and the display module, the factory adjustment for zero point "E" and span "F" is 0 % and 100 %.

A linearization with max. 32 points, based on a table entered either manually or semi-automatically, can be activated locally or remotely. This function provides a measurement in engineering units and a linear output signal for spheres, horizontal cylindrical tanks and vessels with conical outlet.

					Micropilot FMR51, FMR52
	Input
Measured variable	The measured variable is the distance between the reference point and the product surface.
	The level is calculated from this distance, taking into account the empty distance "E" entered by the
	user.
	If required, the level can be converted into other variables (volume, mass) by means of a linearization
	(up to 32 points).
Measuring range	Maximum measuring range
	Device				Maximum measuring range
	FMR51 - standard version				40 m (131 ft)
	FMR51 - with "Advanced dynamics" application package				70 m (230 ft)
	FMR52 - standard version				40 m (131 ft)
	FMR52 - with "Advanced dynamics" application package				60 m (197 ft)
	Usable 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 following tables describe the groups of media as well as the achievable measuring range as a
	function of application and media group. If the dielectric constant of a medium is unknown, it is
	recommended to assume media group B to ensure a reliable measurement.
	Media groups
	Media groups	DC (εr)	Example
	A	1.4 to 1.9	non-conducting liquids, e.g. liquefied gas 1)
	B	1.9 to 4	non-conducting liquids, e.g. benzene, oil, toluene, …
	C	4 to 10	e.g. concentrated acids, organic solvents, esters, aniline, alcohol, acetone, …
	D	> 10	conducting liquids, e.g. aqueous solutions, dilute acids and alkalis

1)Treat Ammonia NH3 as a medium of group A.

For dielectric constants (DC values) of many media commonly used in various industries refer to:

•the Endress+Hauser DC manual (CP01076F)

•the Endress+Hauser "DC Values App" (available for Android and iOS)

LCAUTION

To ensure electrical safety:

Do not disconnect the protective connection.

Disconnect the supply voltage before disconnecting the protective earth.

Connect protective earth to the internal ground terminal (3) before connecting the supply voltage. If necessary, connect the potential matching line to the external ground terminal.

In order to ensure electromagnetic compatibility (EMC): Do not only ground the device via the protective earth conductor of the supply cable. Instead, the functional grounding must also be connected to the process connection (flange or threaded connection) or to the external ground terminal.

An easily accessible power switch must be installed in the proximity of the device. The power switch must be marked as a disconnector for the device (IEC/EN61010).
