Product DescriptionProduct DescriptionE+H FMU30The FMU30 operates on the well - established ultrasonic time - of - flight principle. At its core, the device emits high - frequency ultrasonic pulses from a transducer. These pulses propagate through the air (or the medium above the substance being measured) towards the surface of the liquid, slurry, or bulk solid. When the ultrasonic pulses reach the surface of the target material, a portion of the energy is reflected back towards the transducer.The FMU30 precisely measures the time it takes for the ultrasonic pulse to travel from the transducer to the surface of the material and back. The distance d from the transducer to the material surface can be calculated using the formula, where v is the speed of sound in the medium (which is mainly air in most applications of the FMU30) and t is the time - of - flight of the ultrasonic pulse. Since the speed of sound in air is relatively constant under normal conditions, but can be affected by temperature, the FMU30 has an integrated temperature sensor to account for these variations.1.Design Features1.1 Transducer DesignSensor Sizes and Their SignificanceThe FMU30 is available with two different sensor sizes: 1?" and 2". These sensor sizes are not just a matter of physical dimensions; they have a direct impact on the performance and applicability of the device. The 1?" sensor is well - suited for applications where the maximum measuring distance is relatively shorter. For liquids, it can accurately measure up to 5 m (16 ft), and for bulk solids, it has a maximum range of 2 m (6.6 ft). On the other hand, the 2" sensor is designed for applications that require a longer measuring range. It can measure liquid levels up to 8 m (26 ft) and bulk solid levels up to 3.5 m (11 ft). The larger sensor size allows for a wider ultrasonic beam, which can be beneficial when covering a larger area or when dealing with materials that may cause more significant signal attenuation. The choice between the two sensor sizes depends on the specific requirements of the application, such as the size of the tank or vessel, the type of material being measured, and the presence of any potential obstacles in the measurement path.1.2 Electronics and DisplayAdvanced Signal Processing ElectronicsThe electronics within the FMU30 are designed to handle the complex signals received from the transducer. The ultrasonic pulses that are reflected back from the material surface are weak and may be accompanied by noise, especially in industrial environments with electromagnetic interference. The FMU30's electronics are equipped with advanced signal - conditioning and amplification circuits.These circuits first filter out the unwanted noise, ensuring that only the relevant ultrasonic signals are processed. The signals are then amplified to a suitable level for further analysis. The internal microprocessor in the FMU30 is programmed with sophisticated algorithms to accurately calculate the time - of - flight of the ultrasonic pulses. These algorithms take into account factors such as the shape and intensity of the received signals to improve the accuracy of the measurement. Additionally, the electronics are designed to be energy - efficient, consuming only the necessary power to operate, which is beneficial for applications where power consumption needs to be minimized.2.Technical Specifications2.1 Process - Related Specifications2.1.1 Pressure RangeThe FMU30 is designed to operate within a specific pressure range. It can typically handle pressures from 0.7 to 3 bar (10 to 44 psi). This pressure range makes it suitable for a wide variety of industrial applications. In many liquid storage and processing applications, the pressure within the tanks or vessels falls within this range.The ability to operate within this pressure range also means that the FMU30 can be used in applications where there may be some pressure variations due to normal process operations, such as the filling and emptying of tanks. The device is engineered to maintain accurate level measurements even in the presence of these pressure changes, ensuring reliable performance in different industrial scenarios.2.1.2 Temperature RangeThe FMU30 has a relatively wide temperature range, with an operating temperature range of - 20 °C to +60 °C (- 4 °F to +140 °F). This temperature range allows it to be used in diverse environments. In cold storage facilities, where the temperature may be close to - 20 °C, the FMU30 can accurately measure the level of liquids or bulk solids. Similarly, in industrial plants with hot processes, such as those involving heated liquids or steam, the device can function properly up to 60 °C.The integrated temperature sensor, as mentioned earlier, plays a crucial role in ensuring accurate measurements within this temperature range. It compensates for the changes in the speed of sound due to temperature variations, maintaining the precision of the level measurement. The wide temperature range makes the FMU30 a versatile choice for different industries and applications, eliminating the need for specialized temperature - specific level measurement devices in many cases.2. Measurement - Related Specifications2.2.1 Measuring RangeAs previously mentioned, the measuring range of the FMU30 depends on the sensor size. With the 1?" sensor, it can measure liquid levels up to 5 m (16 ft) and bulk solid levels up to 2 m (6.6 ft). The 2" sensor extends these ranges to 8 m (26 ft) for liquids and 3.5 m (11 ft) for bulk solids. This wide range of measuring capabilities makes the FMU30 suitable for use in tanks and vessels of different sizes.For small - to - medium - sized storage tanks, the 1?" sensor may be sufficient.
