Product Description

Function and measurement system
measuring principle
The MPS3000 series pulse radar level meters are "overhead" measurement systems based on the time-of-flight principle. This instrument measures by emitting a 1mW micro-power microwave pulse from the radar antenna (for example, a 26G frequency radar, which sends a △t-1nS pulse with a 26GHz sine wave signal). The pulse travels through space at the speed of light and reaches the surface of the medium being measured. Part of its energy is reflected back and received by the same antenna. The time interval between the emitted and received pulses is proportional to the distance from the antenna to the surface of the medium.

import
The antenna receives microwave pulse signals reflected from the material surface and transmits them to the electronic component. The microprocessor processes the signal, identifying the echo generated by the microwave pulse on the material surface. Accurate echo signal recognition is completed by intelligent software, with precision reaching the millimeter level. The measurement distance D is proportional to the time travel t of the pulse:
D=c*t/2-- where c is the speed of light
According to the known empty tank value E, the level L is:
The reference point of the empty tank value E in L=E-D-- is shown in the figure above

output
According to the field conditions, the instrument can automatically adapt to the measurement environment by inputting the empty tank height (zero point), full tank height (full scale) and setting the application parameters.
The 4-20mA output is calibrated according to the user's range setting. Communication can be carried out through HART protocol.

Selection guide

·MPS3300 Horn antenna pulse radar can be widely used in the measurement of strong corrosive and complex working conditions of liquids, slurries and other media in storage containers or process containers according to the different horn aperture, such as: water liquid storage tank, acid and alkali storage, slurry storage tank, etc.1) For class A medium, please choose waveguide (20m).

· The MPS3700 series pulse radar can be widely used for the measurement of solid level in process containers with large range according to the different size of antenna opening. For example: coke level, slurry storage tank, solid particles, etc.
 

measuring condition
• The measurement range starts from the point where the beam touches the bottom of the tank. Especially when the storage tank is a disc-bottom tank or the tank body adopts a conical discharge port, the level below this point cannot be measured.
• For media with low dielectric constant (Class A and Class B), if the medium is at a low level (entering the right figure C), the bottom of the tank can be seen. Measurement in this range will reduce the measurement accuracy, so it is recommended to set the measurement zero point at the position of C away from the bottom of the tank (as shown in the figure).
• The theoretical measurement range can reach the end of the instrument antenna. Considering the influence of corrosion and adhesion, the distance between the end of the measurement range and the top of the antenna should be at least A (as shown in the figure). In particular, special attention should be paid when condensation occurs.
Minimum measurement range B is related to the selected antenna type (see table below).
The diameter of the tank shall be greater than D (as shown in the table below), and the height of the tank shall be at least H (as shown in the table below).

· Influence of gas phase
When steam is present on the liquid surface, high pressure will slow down the transmission speed of the signal. This effect is related to the type of steam and is particularly prominent in low temperature environment. When the distance between the measurement zero point (flange) and the material surface increases, the measurement error caused by this effect increases. The measurement error caused by this effect is shown in the following table.

	263	505.4			8.6%
	310	590				22%
	364	687.2					41.8%

Note! When the pressure value is known and constant, the measurement error can be compensated by methods such as linearization.
