Measurement of Liquid Level in Methanol Vertical Internal Floating Plate Storage Tank (φ 14500mm H14300mm)

challenge

1. The customer isMeet the requirements of national and industry regulations, ensure the compliance and safety of tank level monitoring,It is now necessary to install one set of liquid level gauges for each of the 24 vertical internal floating storage tanks.

3. The customer's operating condition is an inner floating disc tank, which is tightly attached to the liquid level and floats up and down in the tank with the rise and fall of the liquid level. Any contact instruments (such as steel strips, servos, floats) that need to be installed vertically from the top of the tank may cause mechanical collision, friction, or jamming with the floating disc,Causing measurement failure or damage to the floating disc, affecting instrument data measurement.

4. The customer's tank area has installed a radar level gauge. If traditional level gauges such as differential pressure and magnetic flip plate are used, additional holes or flanges and waveguide pipes need to be added to the tank wall,Not only does it increase the cost of renovation and the amount of process construction work, but it may also introduce the risk of medium leakage.

Dinghua Solution

The technical support team of Dinghua Electronics understands customer needs and the challenges they are facing. Recommend customers to choose the products launched by Dinghua ElectronicsThe new generation of energy gathering type external liquid level gauge. Its strong signal, high stability, and maintenance free characteristics meet the requirementsCustomers have a demand for safe, accurate, and reliable liquid level measurement.

The energy gathering type external liquid level gauge is mainly designed for harsh working conditions such as vertical storage tanks. Compared with traditional external liquid level instruments,The measurement signal has been significantly improved, which can effectively overcome tank bottom sedimentation, reduce measurement blind spots, and significantly improve stability and accuracy.

1.Compliant with safety regulationsTwo independent systems serve as backups for each other, and any malfunction does not affect monitoring. The signal can be connected to the Safety Instrumented System (SIS).

2.high precisionNot affected by gas phase changes in the medium, providing continuous and stable high-precision (up to ± 1mm) measurements.

3.stable and reliable：Overcome signal interference caused by internal components (baffles, stirrers) and liquid level fluctuations, lock the true liquid level in complex sound fields, and ensure long-term stable data without jumping.

4. Achieve "intrinsic safety" and zero leakage risk: the measurement system is isolated from hazardous media by thick tank walls.

summary

The energy gathering type external liquid level gauge has been successfully installed, debugged, and officially put into use. Practical operation has shown that it exhibits a relatively high level of performanceReliability and stability:

One is to achieve the inside of the tankNon contact, high-precision, real-time continuous monitoring of methanol liquid level;

Secondly, it provides safety interlocking devicesAccurate signal with millisecond level responseGreatly improving the intrinsic safety level of storage tanks;

The successful application of the energy gathering type external liquid level gauge marks a solid step towards smarter and safer tank liquid level management.

Advantages of Energy Gathering External Liquid Level Gauge

1. Fearless of complex working conditions, suitable for vertical tanks

forVertical dome roof tank, floating roof tank, sausage tank, reaction towerUnder the same working conditions, it can effectively overcome interference factors such as self aggregation deposition at the bottom of the tank, even inHigh temperature, high pressure, strong corrosion, high viscosity, highly toxicIt can work stably even in harsh media environments and has a wide range of applications.

2. Signal increase by 20-50 times

The innovative energy gathering sonar signal steering device can focus the vast majority of the emitted energy back onto the probe, and actual application data shows minimal improvement20-50 times the energyEnsure reliable and stable measurement.

3. "Zero blind spots"

Using Xi'an Dinghua ElectronicsSmall blind spot technology+energy gathering technology for blind spot migrationRealize blind spot free measurement.

4. More stable and reliable

It can measure liquids with higher viscosity and is not affected by severe sedimentation at the bottom of the tank, effectively reducing the impact of bubbles and multiple interfering devices inside the container on the measurement.
