Product Description

The measuring principle

FMCW:
Frequency Modulated Continuous Wave
A radar signal is emitted via an antenna, reflected on the product surface and received after a time t. The radar principle used is FMCW (Frequency Modulated Continuous Wave). The FMCW radar emits a high frequency signal whose frequency increases linearly during the measurement phase (called the frequency sweep). The signal is emitted, reflected from the measuring surface and received with a time delay, t. Delay time, t=2d/c, where d is the distance to the product surface and c is the speed of light in the gas above the product. For further signal processing the difference Δf is calculated from the actual transmit frequency and the receive frequency. The difference is directly proportional to the distance. A large frequency difference corresponds to a large distance and vice versa. The frequency difference Δf is transformed via a Fourier transformation (FFT) into a frequency spectrum and then the distance is calculated from the spectrum. The level results from the difference between tank height and measuring distance.

TDR: Time Domain Reflectometry

The guided radar (TDR) level transmitter has been developed from a tried and tested technology called Time Domain Reflectometry (TDR).
The device emits low-intensity electromagnetic pulses of approximately one nanosecond width which are guided along a rigid or flexible conductor. These pulses move at
the speed of light. When the pulses reach the surface of the product to be measured, they are reflected with an intensity that depends on the dielectric constant, εr, of the product (e.g., water has a high dielectric constant and the pulse is reflected back to the transmitter at 80 % of its original intensity).
The device measures the time from when the pulse is transmitted to when it is received: half of this time is equivalent to the distance from the reference point of the device (the flange facing) to the surface of the product. The time value is converted into an output current of 4 to 20 mA and/or a digital signal.
Dust, foam, vapor, agitated surfaces, boiling surfaces, changes in pressure, temperature and density do not have an effect on device performance.

Float type BM26

The magnetic bypass level indicator (MLI) operates on the principle of communicating vessels. The measuring chamber is connected adjacent to the tank so that the same conditions are obtained in the chamber as those in the tank. The float is equipped with a system of permanent magnets to transmit measured values to the local indicator. The magnet system of the float activates either the magnetic flaps according to the liquid level, or a movable follower magnet in the indicating section of the indicator depending on the method of indication chosen. The column of reversed yellow magnetic flaps, or the vertical position of the follower magnet, indicates the liquid level.
