FMP55 Radar Level Transmitter Overview
FMP55 is a high-performance radar level transmitter widely used for liquid level and material level measurement in chemical, petroleum, water treatment, and other industries. Its core advantages lie in non-contact measurement, high precision, and strong anti-interference capability.
This article provides the FMP55 Chinese manual download and explains the working principle, technical parameters, installation and commissioning, and selection points, making it convenient for engineering technicians and procurement personnel to quickly consult.
FMP55 Core Working Principle
FMP55 adopts frequency modulated continuous wave (FMCW) radar technology, calculating the level distance by transmitting high-frequency microwave signals and receiving echoes to determine the frequency difference.
Main Technical Features
- Non-contact measurement: suitable for corrosive, viscous, or high-temperature media.
- High precision: typical accuracy can reach ±2 mm, meeting demanding working conditions.
- Strong anti-interference: supports multiple echo processing algorithms, adapting to complex environments such as stirring and foam.
- Wide range: maximum measuring range can reach 30 meters (depending on antenna and medium).

FMP55 Installation and Commissioning Points
Correct installation and commissioning are key to ensuring the measurement stability of FMP55. The following steps are for reference; for detailed operations, please download the FMP55 Chinese manual.
Installation Steps
- Confirm the installation position avoids interference sources such as feed inlets and agitators.
- Ensure the antenna is perpendicular to the medium surface and leaves sufficient installation space.
- For flange connections, tighten bolts evenly to avoid leakage.
- When wiring, pay attention to power polarity and grounding to prevent electromagnetic interference.
Commissioning Points
- After power-on, use a HART communicator or commissioning software for parameter settings.
- Set the dielectric constant and range according to medium characteristics.
- Use the echo curve function to optimize false echo suppression.
- After completing the settings, perform empty tank and full tank calibration verification.
FMP55 Selection Precautions
During selection, medium characteristics, process conditions, and output requirements must be comprehensively considered to avoid measurement errors or instrument damage caused by improper selection.
- Medium dielectric constant: low dielectric constant media require higher frequency or a stilling well.
- Process temperature and pressure: when exceeding the standard range, high-temperature or high-pressure versions must be selected.
- Antenna material: for corrosive media, PTFE or ceramic antennas should be selected.
- Output and communication: select 4-20 mA, HART, or bus protocol according to the control system.
- Explosion-proof requirements: in hazardous areas, intrinsically safe or flameproof versions must be selected.
