Versatility: It has a variety of measurement functions, including continuous measurement, difference measurement, material identification and temperature compensation, etc., to adapt to different application scenarios and needs.
Reliability and stability: Using advanced technology and design, it has high reliability and stability, can operate stably for a long time in harsh working environment, and reduce the frequency of maintenance and replacement.
2. overall dimensions: the overall dimensions vary with different manufacturers and product models. for details, please refer to the product manual or contact the supplier for detailed information. 3. measurement application range: suitable for non-contact level measurement of liquid, slurry and solid block materials and flow measurement of open channels or measuring weirs,
4. Selection and application scenarios: Select the appropriate model according to actual application requirements. For example, it is suitable for measuring the level of liquid, slurry and solid bulk materials, with a measuring range of up to 10m. At the same time, it is also suitable for flow measurement in open channels or measuring weirs.
5. Installation and wiring: according to the installation instructions provided by the manufacturer for correct installation and wiring. During the installation process, it is necessary to ensure that there are no obstacles between the sensor and the measured object, so as not to affect the measurement results. At the same time, should choose the appropriate cable and connector, and pay attention to prevent wrong or short circuit
6. Precautions for use:
Before use, check whether the appearance and accessories of the instrument are intact
Ensure that the installation direction is consistent with the fluid flow direction to avoid measurement errors
Maintain the instrument regularly and replace the worn parts in time
When the instrument is stopped or replaced for a long time, the instrument should be stored safely, and the power supply and signal line should be removed to avoid electrical safety accidents.
7. Maintenance method:
Regularly maintain the liquid level gauge, clean the housing and sensor of the liquid level gauge, and ensure that the surface of the sensor is clean. Regularly calibrate the liquid level gauge. According to the usage and manufacturer's suggestions, select the appropriate calibration period for calibration operation. When the liquid level gauge is deactivated or replaced for a long time, the instrument should be safely stored, and the power supply and signal lines should be removed.
With the assistance of oscilloscope or multi-purpose instrument, regularly check the output signal and status of the instrument to ensure the normal operation of the instrument
In addition, there are FMU series of level meters from other manufacturers, such as FMU41, FMU42, FMU43 and FMU44. These types of level meters are slightly different in function and performance to meet the needs of different application fields. It is recommended to consult the product manual or consult a professional ten for more information about these models.
The following is an introduction to each model of the FMU series ultrasonic level meter:
FMU40:
Advantages: non-contact measurement using ultrasonic, free from environmental effects such as pollution, corrosion and high temperature. Four lines of plain text display menu-style field operation, fast and simple instrument debugging. With 7 optional languages, on-site envelope display, simple instrument fault diagnosis. The FieldCare operation software is provided so that the user can easily operate the instrument remotely, diagnose faults and document the measuring points. Suitable for use in explosion hazardous areas (gas-Ex, dust-Ex). The linearization function of up to 32 points can convert the measured value into any unit of length, volume or flow rate. The external dimension: 50mm E H.
Measuring range: 0.3~10 meters
Installation and use: probe installation must be higher than the maximum liquid level of 40~60cm, to avoid entering the instrument blind area, the probe to avoid direct sunlight, to ensure that the environment
Consistent temperature to ensure accurate measurements
Maintenance, regular cleaning or replacement of the filter element or electrode in the sensor and signal transmitter, to maintain its cleanliness. Regularly check whether the connecting pipe is loose or leaking, and tighten or replace the seal in time. According to the use of a comprehensive inspection and maintenance of the flow meter on a regular basis to ensure its normal operation.
FMU41:
Economical level measuring instrument, suitable for liquid and solid bulk material level measurement under complex working conditions
Measuring range: up to 8 meters
Overall dimensions: 50mm E H.
FMU42:
Suitable for non-contact level measurement of liquids, slurries and solid blocks, as well as flow measurement in open channels or measuring weirs. Linearization function (up to 32 points) can convert the measured value into any unit of length, volume or flow. It is suitable for continuous non-contact level measurement of liquid, slurry, sludge and solid blocks, flow measurement of open channel and measuring weir, system integration: HART (standard),4...20mA,PROFIBUS PA,FF foundation fieldbus; Maximum measuring range: liquid 5 m, solid 2 m.
FMU43:
Economical level measuring instrument, suitable for liquid and solid bulk material level measurement under complex working conditions. Maximum measuring range: liquid 15 meters, solid 7 meters.
FMU44:
The economical level measuring instrument is suitable for the level measurement of liquid and solid bulk materials under complex working conditions. The maximum measuring range is 20 meters for liquid and 10 meters for solid.
Integrated design, the sensor and signal transmitter are installed in the probe, compact structure, no external wiring between the sensor and the signal transmitter, reducing signal loss, strong anti-interference ability, can be displayed on the spot. It has the characteristics of high measurement accuracy and strong anti-interference signal ability, and is widely used in the measurement of various storage tank liquid levels. The installation of the integrated level gauge instrument is very convenient, and the thread and nut on the probe can be directly fixed on the tank item through the flange or installed on the bracket and riser.
