Verified! This differential pressure flow meter reduces heat tracing energy consumption by over 90%, saving tens of thou

In the northern winter, inspectors brave sub-zero temperatures to repeatedly check steam tracing pipelines for freezing; in oil refineries, unplanned shutdowns due to pressure pipe leaks are frequent; in solar thermal power plants, the energy consumption for heat tracing in high-temperature molten salt measurements is alarmingly high. According to industry statistics, the annual maintenance cost of a traditional heat-traced differential pressure flowmeter exceeds 10,000 yuan, with as many as 8-12 welded leak points, and energy consumption accounting for more than 90% of the entire measurement system.

High energy consumption, numerous leak points, and cumbersome maintenance—these three major pain points have plagued the industry for decades. This is not a measuring tool; it is clearly a "cost black hole" and a "time bomb."

Faced with this "old problem" that has remained unsolved for decades, the industry's common approach is to optimize heat tracing materials, improve insulation structures, and increase the frequency of inspections. But these are all "treating the symptoms, not the root cause." The fundamental reason for the existence of heat tracing systems is that the pressure guide pipes are too long and the medium is prone to condensation. As long as the pressure-conducting pipe remains, the heat tracing system cannot be eliminated, unless—the pressure-conducting pipe is removed. So, are there any solutions in the industry that can truly solve these problems? Keyang Technology's A+K heat-free differential pressure flow meter offers a brilliant answer. Its core logic is not to optimize heat tracing, but to eliminate the need for heat tracing altogether. With its revolutionary integrated design, the A+K heat-free differential pressure flow meter makes electric and steam heat tracing obsolete, bringing a truly cost-effective solution to industrial customers worldwide.

• No Heat Tracing Required, Saving 90% on Energy Costs Annually:

  Through its unique short-pressure-conducting and non-pressure-conducting structure, combined with a high-temperature dual-chamber transmitter, it completely eliminates dependence on heat tracing. Whether in the frigid temperatures of -45°C in the north or the molten salt temperatures of 780°C in solar thermal power generation, the flow meter operates stably without any heat tracing. This alone can save users tens of thousands of yuan in energy costs annually, truly achieving "one-time investment, long-term benefit."

• Integrated Design, Leakage Points Reduced by 80%

  Traditional flow meters are assembled from more than a dozen components, including primary elements, pressure guide pipes, valve assemblies, and transmitters. The A+K heat-tracing-free flow meter integrates all components into a single design, simplifying the product structure and significantly reducing leakage points. This means there's no longer any need to worry about pressure guide pipe leaks or internal valve leaks, resulting in a qualitative leap in measurement safety and stability.

• Dual Diaphragm Technology, the "Stabilizing Force" for High-Temperature Measurement

  For high-temperature conditions, the A+K heat-tracing-free flow meter adopts an integrated front and rear dual diaphragm structure. The high-temperature medium first contacts the front diaphragm, and the pressure is transmitted to the rear diaphragm through specially designed micro-pressure guide holes, achieving staged cooling. The micro-pressure guide holes between the upper and lower diaphragms not only ensure the accuracy and stability of pressure transmission but also significantly reduce temperature response time, making high-temperature measurements more accurate and reliable.

• Multiple filling fluids covering all operating conditions with media temperatures ≤780℃.

  Keyang Technology offers a variety of high-temperature resistant filling fluids, including 315℃, 380℃, 400℃, 420℃, and 780℃, which can be flexibly selected according to the temperature characteristics of different operating conditions. Whether it's crude oil in the oil refining industry or liquid metal in the nuclear power industry, the most suitable solution can be found.

Some may ask: Will the measurement accuracy be compromised by eliminating heat tracing? The answer is: Not only is it not compromised, but it's actually more reliable. Moreover, compared with traditional solutions, its advantages are significantly enhanced.

A+K heat-tracing-free flow meters have been implemented in multiple industries, including northern steam, concentrated solar power (CSP), oil refining, and nuclear power, solving long-standing heat tracing problems for users.

• Steam Flow Measurement in Northern China:

  In northern winters, traditional steam flow meters often suffer from inaccurate measurements due to frozen pressure lines. The A+K heat-tracing-free flow meter requires no heat tracing and operates stably even at extreme temperatures as low as -45°C, completely eliminating the freezing problem.

• High-Temperature Molten Salt Measurement in CSP:

  CSP plants have molten salt temperatures as high as 565°C. Traditional flow meter heat tracing systems are not only energy-intensive but also have a high failure rate. The A+K heat-tracing-free flow meter uses a 780°C high-temperature resistant filling fluid and a double-diaphragm structure, perfectly solving the measurement challenges of high-temperature molten salt.

• Fresh Oil Measurement in Oil Refining:

  Oil refineries have high-temperature, high-viscosity feedstocks, making traditional pressure lines prone to clogging. The A+K heat-free flow meter's short pressure tap structure significantly reduces the media's residence time in the pressure-conducting pipe, effectively preventing blockages and improving measurement reliability.

• Nuclear Power Industry Liquid Metal Measurement:

  The nuclear power industry has extremely high requirements for the safety and stability of measuring equipment. The A+K heat-free flow meter's all-welded structure and zero-leakage design fully meet the stringent standards of the nuclear power industry and has been applied in multiple nuclear power projects.
