How Is a Flow Monitor Adjusted in an Oil-Air Lubrication System?

In an oil-air lubrication system, the flow monitor is used together with an electronic monitoring device to continuously supervise lubricant flow. Its primary function is to ensure that the required amount of lubricant is being delivered to the lubrication points.

When the oil supply is interrupted, reduced, or blocked, the pulse signal generated by the flow sensor will decrease or stop. The electronic monitoring unit will then immediately issue an alarm or fault signal, allowing operators to identify and address the problem before lubrication failure occurs.

Flow Monitor Adjustment Method

During system operation, the flow monitor can be adjusted by changing the sensing area (sensitivity setting) of the flow sensor. This adjustment determines the number of pulses detected within a specific period of time.

The adjustment should be carried out according to the following principle:

✅ The monitoring system should accurately detect normal lubricant flow and generate the expected pulse count.

✅ When the system output pressure falls below the specified value, the monitor should be able to identify the abnormal condition.

✅ When no lubricant passes through the pipeline (for example, due to a blocked outlet or pipeline obstruction), the pulse signal should stop, triggering a fault alarm.

Why Proper Adjustment Is Important

Correct flow monitor settings help ensure:

Reliable lubricant delivery
Early detection of pipeline blockages
Immediate warning of lubrication failures
Improved equipment protection
Reduced risk of bearing or component damage

By properly adjusting the flow sensor sensitivity and pulse threshold values, the oil-air lubrication system can provide accurate real-time monitoring and ensure stable, safe operation of the entire lubrication process.
