⚙️ Mechanism of Operation and Types of Pressure Gauges
Basic Types
Industrial pressure gauges rely on several technologies. The most common type is the Bourdon Tube Gauge, suitable for medium and high pressure. Other types include:
| Type | Application |
|---|---|
| Bourdon Tube Gauge | Medium and high pressure (most common) |
| Diaphragm Gauge | Low pressures |
| Capsule Gauge | Very low pressures |
| Digital Gauge | High accuracy with electronic display |
| Manometer | Traditional device for measuring fluid pressure |
Glycerin-Filled Gauges
These are mechanical gauges filled with glycerin to absorb vibrations and shocks, extending their lifespan and ensuring accurate readings. They are widely used in fire pumps and heavy industrial systems.
🔥 Applications of Pressure Gauges in Fire Protection Systems
Pressure gauges are used in several critical applications within fire protection systems:
| Application | Description |
|---|---|
| Portable Fire Extinguishers | Mounted on the extinguisher to monitor internal pressure, ensuring readiness for immediate use |
| Fire Piping Networks | Measure pressure in sprinkler networks and fire hydrants to ensure adequate water reaches all points |
| Fire Pumps | Mounted on discharge and suction lines of main and jockey pumps for real-time pressure monitoring and performance adjustment – Glycerin-filled gauges are especially used due to their vibration resistance |
| Height | 20.86 cm |
| Width | 34.64 cm |
| Weight | 11.92 cm |
| Power | 71.58 cm |
| Speed | 97.31 cm |
✅ Original packaging: Stamped box with Hydranautics logo and model number
✅ Serial number: The presence of a unique serial number (which can sometimes be verified via the distributor)
✅ Print quality: clear, non-eraseable logo and symbols
✅ Instant performance: Noticeable reduction in salt content (TDS) from first use
✅ Certification: Existence of certified quality certificates (ISO, NSF)
Answer: (Necessary to maintain the life of the membrane)
Sand or mesh filter to remove large plankton
Activated carbon filter to remove chlorine and chloramine (very important)
Water softener (Softner) if the water is hard
1-5 micron fine filter as the final stage before the membrane
