Selecting the correct pressure range on a pressure gauge is essential to ensure accurate readings, operational security and greater durability del instrument.
What should be the ideal range?
The manometer scale range should be twice the operating pressure, so that this remains between the 25% and 75% full scale.
- This ensures that the reading midpoint is close to 12 o’clock on the dial, facilitating clear reading.
- If they exist pulsations or pressure spikes, the operation value must not exceed 50% of range total of the pressure gauge.
Why is it so important?
- Reduces the mechanical stress of the instrument.
- Improves reading accuracy.
- Extends the life of the pressure gauge.
- Minimizes the risk of failures and overpressure.
Additional recommendations:
- Install snubbers if there are pulsations.
- Use diaphragm seals for aggressive media.
- Implement cooling towers or siphons to work with steam or elevated temperatures.
- Consider the reading angle: the scale must be readable from the operator’s position.
