Industry Information
Excellent product performance and service quality since the operation of delta flowmeter

盐行业复苏给流量测量带来了更多机会和挑战。 The demand for industrial salt is constantly increasing, and the technological transformation and expansion of a salt-producing company as the main salt-producing unit is to expand the production. The recovery of the salt industry of delta meter brings more opportunities and challenges to flow measurement. Small pipeline power loss (small pressure loss): The pressure loss of the average speed tube is much smaller than that of the orifice plate, only 5 ~ 10% of the orifice plate; on the other hand, due to the small pressure loss, the differential pressure will be small. (The pressure difference between high pressure and low pressure) makes the requirements for selecting a differential pressure transmitter increase and the cost increases, otherwise the output accuracy of the transmitter will be lowered because the range cannot be achieved. Therefore, a good probe must take into account both pressure loss and differential pressure. The surface design of HLVD Delta Taba fully considers this factor, the cross section itself is symmetrical, the surface is divided into three parts (as shown below), and the facing face is divided into smooth sections to make the probe smoothly contact the medium; the second part is the acceleration section. Accelerate the flow velocity of the medium three times on average, and increase the pressure on the oncoming section by increasing the contact surface with the medium; the third part is the high and low pressure boundary spikes, and the sudden resistance disappears, forming a low pressure area behind the probe, and the actual color velocity spectrum can be sufficient Reflects the change in the flow rate of the medium. Therefore, the design of the WYHLVD Delta Tab probe meets the requirements of small pressure loss and large differential pressure. The distance between the power plant and the salt-making plant of the Salinization Company is more than 2000 meters. The steam transmission pipeline is too long. The orifice flowmeter was originally used. However, the measurement accuracy and pressure loss have a great impact on the measurement and transmission of steam. There is a large difference in the gas output of the power plant; at the same time, there is a large error between the measured gas output of the orifice plate and the theoretically calculated gas volume, which seriously affects the normal gas consumption of the salt plant and the economic benefits of the power plant.
问题,公司技术人员对多家流量计厂家提供方案进行评估,同时对产品应用情况进行考察,最终确定了KENDTB德尔塔巴流量计。 2. The measurement solution solves the problem of Delta Taba flowmeter. The company's technicians evaluate the solutions provided by multiple flowmeter manufacturers and inspect the application of the product. KEDTB Delta Taba flowmeter is a kind of averaging tube flowmeter manufactured by German Kener company. The flow meter belongs to the differential pressure working principle and the plug-in working mode, which can be used for gas, liquid and steam flow measurement. It has the outstanding advantages of simple structure, small pressure loss, convenient installation and maintenance, etc. It is a high-precision flow sensor, which can be used under severe working conditions, and can maintain good measurement performance. The user's on-site process conditions accurately measure the main steam flow and saturated steam flow of the boiler. This section has installed more than 20 KEDTB Delta Taba plug-in flow meters to replace the previous nozzle and orifice plate measuring devices.

Installation and application

1. Easy installation. When the flowmeter is installed, only a 28mm small hole needs to be drilled in the measuring pipe and the mounting bracket is welded to complete the instrument installation. The entire installation process does not exceed one hour, and is particularly suitable for technical transformation projects. 2. The measurement is accurate and stable. The problem of steam measurement has always troubled the power plant and the salt plant, which has become a big problem. The application of KEDTB Delta Taba flowmeter completely solves the problems of unstable steam volume and inaccurate metering in the salt making workshop. 3. Small pressure loss is another outstanding advantage of this product. The pressure loss of this product is only 5-10% of the orifice plate flowmeter, which is almost negligible. The small pressure loss makes the boiler increase the steam output, and also makes the boiler and steam transmission pipelines run more safely and reliably.
four. 运行以来,优良产品性能和服务质量到盐化公司充分肯定,同时,也在其他制盐行业到了较广泛推广应用。 Concluding remarks Since the operation of the KEDTB Delta Taba flowmeter , the excellent product performance and service quality have been fully affirmed by the salinization company. At the same time, it has also been widely used in other salt-making industries. Practice has proved that the application of the KEDTB Delta Taba flowmeter in the salt industry is feasible, which has promoted the improvement of the steam measurement management level, and also created good economic benefits for the enterprise.
