Micropilot FMR60

Measuring principle

The Micropilot is a "downward-looking" measuring system, operating based on the frequency modulated continuous wave method (FMCW). The antenna emits an electromagnetic wave at a continuously varying frequency. This wave is reflected by the product and received again by the antenna.

A0032017

 1 FMCW principle: transmission and reflection of the continuous wave

R Reference point of measurement D Distance between reference point and product surface

The frequency of this wave is modulated in the form of a sawtooth signal between two limit frequencies f1 and f2:

 2 FMCW principle: result of frequency modulation

1 Transmitted signal 2 Received signal

This results in the following difference frequency at any time between the transmitted signal and the received signal:

Δf = k Δt

where Δt is the run time and k is the specified increase in frequency modulation.

Δt is given by the distance D between the reference point R and the product surface:

D = (c Δt) / 2

where c is the speed of propagation of the wave.

In summary, D can be calculated from the measured difference frequency Δf. D is then used to determine the content of the tank or silo.

Input

Measured variable

The measured variable is the distance between the reference point and the product surface. The level is calculated based on "E", the empty distance entered. Optionally, the level can be converted to other variables (volume, mass) by linearization (32 value pairs).

Measuring range Maximum measuring range

Device Antenna

FMR60 GA:

Drip-off, PTFE 50 mm / 2"

1) Feature 070 in the product structure

Usable measuring range

The usable measuring range depends on the antenna size, the medium's reflective properties, the installation position and any possible 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 group DC (εr) Example

A0 1.2 to 1.4 Butane, liquid nitrogen, liquefied hydrogen

A 1.4 to 1.9 non-conducting liquids, e.g. liquefied gas

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

Maximum measuring range

50 m (164 ft)

1) NH3 falls into medium 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)

Overvoltage protection

• Devices without integrated overvoltage protection Pluggable spring-force terminals for wire cross-sections 0.5 to 2.5 mm2 (20 to 14 AWG)

• Devices with integrated overvoltage protection Screw terminals for wire cross-sections 0.2 to 2.5 mm2 (24 to 14 AWG)

• For ambient temperature TU≥60 °C (140 °F): use cable for temperature TU +20 K.

HART

• A normal device cable suffices if only the analog signal is used.

• A shielded cable is recommended if using the HART protocol. Observe grounding concept of the plant.

If the measuring device is used for level measurement in flammable liquids which requires the use of overvoltage protection according to DIN EN 60079-14, standard for test procedures 60060-1 (10 kA, pulse 8/20 μs), an overvoltage protection module has to be installed.

• Temperature = +24 °C (+75 °F) ±5 °C (±9 °F)

• Pressure = 960 mbar abs. (14 psia) ±100 mbar (±1.45 psi)

• Humidity = 60 % ±15 %

• Reflector: metal plate with diameter ≥ 1 m (40 in)

• No major interference reflections inside the signal beam

Typical data under reference operating conditions: DIN EN IEC 61298-2 / DIN EN IEC 60770-1; percentage values in relation to the span.

Output: digital analog

Accuracy (Sum of nonlinearity, nonrepeatability and hysteresis)

Non-repeatability

1) Add error of the analogous value to the digital value.

2) If the reference conditions are not met, the offset/zero point arising from the mounting conditions may be up to ±4 mm (0.16 in). This additional offset/zero point can be compensated for by entering a correction (parameter "level correction") during commissioning.

3) The non-repeatability is already considered in the accuracy.

Dead band according to DIN EN IEC 61298-2 / DIN EN IEC 60770-1:

• Digital: 1 mm

• Analog: 1 µA

Response time

The response time can be configured. The following step response times (in accordance with DIN EN IEC 61298-2 / DIN EN IEC 60770-1)

are when damping is switched off:

2) According to DIN EN IEC 61298-2 / DIN EN IEC 60770-1, the step response time is the time that elapses after an abrupt change in the input signal until the change in the output signal has adopted 90% of the steady-state value for the first time.
