Float and Board Type Level Gauge
Float and board type level gauges are an efficient and reliable solution for monitoring liquid levels in large storage tanks, particularly in industries that require precise, continuous level measurements. This gauge system is simple yet highly effective, offering a clear and visible indication of the liquid level inside a tank. In this blog, we’ll explore the essential features, working principles, applications, and benefits of float and board type level gauges.
What is a Float and Board Type Level Gauge?
A float and board type level gauge is a mechanical device designed to measure the level of liquids in large storage tanks or vessels. This gauge consists of a float attached to a pointer and a scale. As the liquid level rises or falls within the tank, the float follows suit, and this movement is transmitted to the pointer, which travels along the scale, showing the precise level.
This gauge type is especially valuable in applications where electronic or more complex systems may not be feasible, due to either operational conditions or budget constraints.
How Does a Float and Board Type Level Gauge Work?
- Float Mechanism: A float, typically made from corrosion-resistant materials, is placed on the liquid surface inside the tank. The float’s buoyancy allows it to follow the rise and fall of the liquid.
- Guide Wires or Pipes: The float is usually attached to a wire or rope, which helps guide its vertical movement as the liquid level changes.
- Pointer and Scale: The float is connected to a pointer that moves up and down on a graduated scale located on the outside of the tank. As the liquid level rises, the pointer moves upwards along the scale, providing a clear and easily visible reading of the level.
- Counterweight: A counterweight on the opposite side of the float ensures balance and smooth movement along the scale.
Key Advantages of Float and Board Type Level Gauges
- Low Maintenance: This gauge type has a straightforward mechanical design, making it easy to maintain with minimal technical requirements.
- High Visibility: The scale is easily readable, allowing for quick visual checks from a distance.
- Reliability in Harsh Environments: Float and board gauges are built to withstand industrial conditions, including exposure to extreme temperatures, pressures, and corrosive liquids.
- Cost-Effective: With no electronic components, these gauges are typically more affordable than advanced digital systems, making them ideal for industries with budget constraints.
Applications of Float and Board Type Level Gauges
- Water Treatment Plants: For monitoring water levels in large storage tanks.
- Chemical Processing: Used in tanks that hold corrosive or hazardous chemicals due to the gauge’s durable construction.
- Oil & Gas Industry: Ideal for storage tanks where continuous level monitoring is necessary for operational safety.
- Agricultural Facilities: Used to monitor liquid levels in storage tanks for irrigation or other processes.
Choosing the Right Float and Board Type Level Gauge
- Tank Size: Ensure the gauge scale can accommodate the maximum and minimum levels of the tank.
- Liquid Density: The float should be able to handle the density of the liquid without sinking.
- Environmental Conditions: Consider the material of the float and other components if the gauge will be exposed to corrosive chemicals, high temperatures, or other extreme conditions.
Installation and Maintenance Tips
- Installation: Ensure that the guide wires or pipes are straight and securely attached to the tank. Misalignment can lead to inaccurate readings or cause the float to stick.
- Cleaning: Periodic cleaning of the float and scale is necessary to prevent the accumulation of residues that can affect accuracy.
- Calibration: Regular calibration checks help maintain measurement precision, particularly if the gauge is exposed to varying temperature or pressure conditions.
