Mechanical Level Indicator

What is Mechanical Level Indicator? How it works and what are benefits of directly proportional reading. 

Mechanical level indicators are critical for managing liquid levels in elevated water tanks, particularly in contexts where accuracy and reliability are paramount. These indicators must function without reliance on electrical power and offer clear readability from significant distances—especially vital for firefighting brigades and operation and maintenance crews. M&I Est. has developed (MEQIAS) Mechanical Level Indicator and revolutionized this field with, featuring directly proportional reading (DPR) technology, ensuring both precision and ease of use.  

Elevated water tanks, found in various applications from military complexes to public infrastructure, traditionally employ mechanical level rulers with pointers to indicate the liquid level within. These indicators must be easily readable from afar, crucial for swift and effective response by relevant personnel. Conventional mechanical level indicators often use inversely proportional reading concept, which can lead to confusion and some time inefficiency. 

MEQIAS addresses these challenges by offering a novel mechanical level indicator with directly proportional reading (DPR), making liquid level measurement intuitive and straightforward according to true water level in side tanks.

Unique DPR Technology

MEQIAS Mechanical Level Indicators utilize a directly proportional reading technique. In practical terms, if the water level in the tank rises by 10 cm, the external red marker on the ruler ascends by the same 10 cm, maintaining a direct correlation between the internal water level and the external reading. This is a significant advancement over traditional indicators that use inversely proportional reading, where the external marker's position is inversly correspond to the actual water level. 

Operating Principle

The MEQIAS indicator operates using a float-cylinder mechanism that moves up and down with the liquid level inside the tank. This float is connected to a stainless steel wire rope, which interacts with two special mechanisms located at the tank's top and bottom. These mechanisms guide a counterweight that travels up and down along aluminium purlins (gauge board) mounted outside the tank. The gauge board features clear, directly proportional markings, allowing for immediate visual confirmation of the water level.

Material and Durability

Crafted from high-quality stainless steel, including the bearings, the MEQIAS indicator is designed to endure harsh conditions. The robust construction allows the mechanism to function smoothly and maintain accuracy, even when fully immersed in liquid for extended periods. The system's resilience ensures a defect-free and maintenance-free operation over its lifespan.

Applications 

The MEQIAS Mechanical Level Indicator is suitable for various applications, including: 

Military complexes 

Housing cities 

Industrial areas 

Civil defence stations 

Public elevated tanks 

Its versatility extends to atmospheric tanks, low-pressure tanks, and reservoirs, making it ideal for medium storage tanks and bulk storage scenarios.

Special Features of MEQIAS Mechanical Level Indicators 

Directly Proportional Reading (DPR) 

One of the standout features of the MEQIAS Mechanical Level Indicator is its directly proportional reading (DPR) capability. Unlike conventional mechanical level indicators that use inversely proportional reading—where the external pointer might rise as the water level falls and vice versa—MEQIAS ensures that the pointer's position on the gauge board directly correlates with the actual water level inside the tank. This means that if the water level decreases by a certain amount, the external pointer moves down by the same amount. This one-to-one correspondence simplifies reading and interpretation, reducing the potential for errors and enhancing logical operational efficiency.

Robust Design and Premium Materials 

The MEQIAS Mechanical Level Indicator is built to last, incorporating high-quality materials like stainless steel for critical components, including the float, wire rope, and bearings. This robust design ensures that the indicator can withstand harsh environmental conditions and operational stresses. The use of stainless steel not only prevents corrosion but also guarantees smooth and reliable operation over long periods, even when the mechanism is fully submerged in liquid. This premium build quality translates to minimal maintenance requirements, reducing downtime and maintenance costs for users.

Versatility Across Tank Types 

Whether your storage tanks are made of concrete or metal, the MEQIAS Mechanical Level Indicator is designed to be compatible. This versatility is crucial for various industries and applications, where tank materials can vary widely. The system can be securely bolted to concrete tanks or welded to steel tanks using suitable brackets, ensuring a solid and stable installation. This flexibility makes MEQIAS a versatile solution for a broad range of storage tank configurations. 

Clear and Legible Readings 

The MEQIAS indicator features an 8-inch net-reading-width measuring ruler (purlins), which provides a large, easily readable display of the liquid level. The gauge board is marked off in meters, with clear graduations and numbering e.g. (0, ¼, ½, ¾, and 1) that allow for quick and accurate reading of the water level. The red-colored counterweight enhances visibility, making it easy to read the level from a distance, an essential feature for operational efficiency and safety.

Suitable for Various Liquids 

The MEQIAS Mechanical Level Indicator is designed to handle virtually any type of liquid, making it a versatile choice for different storage needs. Whether dealing with water, chemicals, or other fluids, the indicator's design ensures accurate and reliable performance. This adaptability makes MEQIAS suitable for a wide range of applications, from industrial processes to municipal water systems.
