What are the requirements for the front and rear straight pipe sections of the elbow flowmeter?

Answer: The straight pipe section requirements for 90-degree and 135-degree elbow flowmeters are 5D in front and 2D in the back, and the straight pipe section requirements for 180-degree elbow flowmeters are 10D in front and 5D in the back. What are the

specific installation requirements for elbow flowmeters?

Answer: The installation of elbow flowmeters is a very important link. It is related to whether the elbow flowmeter can be used normally and whether its accuracy can be guaranteed.
First of all, when installing the elbow sensor, ensure that the pressure taking bodies on both sides are on the same horizontal plane. In addition, the overall elbow sensor should be kept horizontal. If the steam is measured, when the disc condenser is installed next, the overall horizontality of the discs on both sides and the characteristics on the same horizontal plane must be ensured.
The installation of other components can refer to the corresponding instructions.

Why is the elbow flowmeter an energy-saving product?

Answer: The elbow flowmeter is a differential pressure flow meter. Its core pressure-taking component, the elbow sensor, does not have any inserts or flow-blocking parts. During use, it only needs to replace the original elbow at the bend of the pipeline. Therefore, it will not produce additional pressure loss, and it is an energy-saving product compared with other flow meters. This is of great significance for the medium with low conveying power in industry.

Does the FCWL elbow flowmeter have an output function?

Answer: The main unit of the FCWL elbow flowmeter can be equipped with 4-20MA, RS232, and RS485 interfaces. In addition, Adam modules, DCS, PLC and other modes can also be provided.

What media are suitable for measuring with elbow flowmeters?

Answer: As long as it is a low-viscosity medium, the elbow flowmeter can accurately measure it. Due to the characteristics of the elbow flowmeter itself, the media that are more suitable for measurement include steam (superheated and saturated steam), circulating water for heating, chilled water for air conditioning and refrigeration units, various gases (blast furnace, coke oven, converter gas), compressed air, natural gas, sewage, etc.

What are the media that the elbow flowmeter has successfully measured today? What are the fields of design?

Answer: The media that the elbow flowmeter has successfully measured include heating water, superheated steam, saturated steam, chilled water, blast furnace gas, coke oven gas, converter gas, compressed air, combustion air, induced draft, sewage, liquid ammonia, nitrogen, oxygen, acetylene, diesel, transformer oil, natural gas, dehydrogenation tail gas, etc.; the fields of application include heat, thermal power, steel metallurgy, coking gas, tobacco, petrochemical, papermaking, food processing, environmental protection, building materials and other fields.

What are the indicators of an ideal flowmeter? How to evaluate the elbow flowmeter according to the indicators of an ideal flowmeter?

Answer: The index conditions of an ideal flow meter are as follows:
1. The detection part has no obstructions;
2. The detection part can be clamped on the outside of the pipeline and can be moved at will to any location for measurement without cutting off the pipeline and the fluid;
3. The flow calculation equation of the instrument is simple and clear, and can be extrapolated to unknown areas without actual flow verification;
4. The frequency pulse output signal and digital instrument are convenient for remote transmission, anti-interference and connection with computers;
5. The instrument output signal is not affected by the physical properties of the fluid medium;
6. The instrument output signal is not affected by the flow characteristics of the fluid;
7. The instrument has good repeatability;
8. The instrument has a wide range and good linearity;
9. The instrument has high reliability, moderate price, and simple maintenance technology;
10. No individual actual flow verification is required, or only "dry calibration" is required, or verification in one or two media can be extended to other media;
11. The output signal of the detection part directly reflects the mass flow rate.
To be honest, the elbow flowmeter is the one that matches the ideal flowmeter most among all flowmeters. Except for the second item, the other items are partially or completely met.

The elbow flowmeter has requirements for the on-site environment. Is it afraid of vibration?

Answer: The primary element of the elbow flowmeter, the elbow sensor, has no special requirements for the on-site environment and can be used under general industrial on-site conditions. The host meter of the elbow flowmeter is generally required to be away from strong interference sources. The signal line is best to use a shielded line and is laid separately from the power line (consistent with other host meters). There are no special requirements.

What is the price of the elbow flowmeter?

Answer: The price of the elbow flowmeter is slightly higher than that of the orifice flowmeter. The gap narrows as the pipe diameter increases, but in view of the no pressure loss and maintenance-free characteristics of the elbow flowmeter, its cost performance is unmatched by the orifice flowmeter.

The elbow flowmeter is an energy-saving flow meter. How is its energy-saving data calculated?

Answer: Compared with differential pressure flowmeters such as orifice plates, the elbow flowmeter has no additional pressure loss and is energy-saving. The calculated value is also based on this. If the flow rate is 600t/h, the pressure loss through the orifice flowmeter is 1mH2O column. If an energy-saving flowmeter such as an elbow is used, the energy saved is equivalent to 600×103×1×9.8=5880000 joules, which is equivalent to nearly 1.65 degrees of electricity. If it runs all day, it can save nearly 40 degrees of electricity every day. The introduction here is only about power consumption. The energy loss caused by the reduction in the quality of the transported energy due to pressure loss varies from industry to industry and is not covered here. In summary, the cost of the elbow flowmeter can be recovered within one year through the benefits brought by energy saving.

What is the accuracy level of the elbow flowmeter?

Answer: Nowadays, the system accuracy of the elbow flowmeter can be guaranteed to be within 1.5 levels (the accuracy of the specially processed elbow sensor can reach 1.0 levels). It has been confirmed both in practice and in the process of actual flow calibration. The theory and application technology are already quite mature and there is no big doubt. This is inseparable from the hard research of many experts and scholars and the extensive practical work of many elbow flowmeter manufacturers. It is also inseparable from modern pipe bending processing technology and the ever-changing computer technology (especially single-chip microcomputer technology).

How is the understanding process of elbow flowmeter?

Answer: The elbow has appeared in the field of industrial application as a flowmeter for more than a hundred years. Textbooks on flow meters and national differential pressure flowmeter calibration procedures have introduced it as a type of differential pressure flowmeter. However, the understanding of the characteristics of this flowmeter is different in different eras, and some views are even diametrically opposed. This is mainly concentrated in terms of accuracy, geometric calibration or real flow calibration, and installation straight pipe section requirements. However, the understanding of the flowmeter's no pressure loss, high reproducibility (0.2%), and no obvious effect of scaling and wear on accuracy is completely consistent.

What are the forms of elbow flowmeters?

Answer: Since the development of elbow flowmeter, the specific types commonly used in industry include elbow flowmeter for 90° bend (90° elbow with R/D=1.5 and 45° pressure measurement), 180° elbow flowmeter for straight pipeline (some manufacturers call it S type), and elbow flowmeter for 135° pipeline connection. The dominant type is 90° elbow flowmeter. Our company's elbow flowmeter products have been serialized, and customers are welcome to consult.

How to choose between temperature components and pressure transmitters?

Answer: Whether temperature components and pressure transmitters are needed depends on the situation. Generally, they must be equipped for superheated steam, and only temperature components are required for saturated steam. The principles for other media are as follows: temperature and pressure have a great impact on the density of the medium, so they are generally required to be equipped; the temperature and pressure fluctuation range is large, so they are generally required to be equipped; the accuracy requirements for the metering medium are high, so they are generally required to be equipped; if there are requirements for heat measurement, temperature components are required (end)
