SENCTRL 0-15 Psi Low Pressure Gauge

The SENCTRL low pressure gauge features a 2″ dial enclosed in a 304 stainless steel case for corrosion resistance and IP67 waterproof ratings to resist condensation and fogging. Brass and stainless wetted parts enable use with non-corrosive liquids and gases, including air and water pressure tests. Its construction suits ATV tire testing, HVAC piping, and general pressure measurement in portable heater setups.
Key points: 0-15 psi range offers adequate monitoring for most torpedo heater auxiliary lines; the robust enclosure aids durability in rugged environments; stainless and brass wetted parts improve longevity in moist or damp spaces. For installations requiring clear readability and weather resistance, this gauge aligns well with standard low-pressure applications.
MEASUREMAN Heater Heavy Liquid Filled Gauge

This heavy liquid-filled gauge emphasizes reliability for heater diagnostics. It supports accurate readings with a large 2-1/2″ dial and is designed for low-pressure monitoring in portable oil-fired heaters. Its installation involves threading the nipple into a prepared hole and using a filled system to dampen pointer flutter during vibrations. Proper calibration and leak checks with soapy water are recommended during setup.
Notes: The gauge is positioned to read pressure efficiently while resisting pulsations common in burner operations. The included relief concepts help manage excess pressure and ensure safe operation during testing or routine checks of the heater’s air pump and flow system.
MEANLIN MEASURE 0~15Psi Stainless Steel Gauge

This 1/8″ NPT, 1.5″ dial stainless steel liquid-filled pressure gauge offers back-mount installation, making it suitable for compact heater compartments. Glycerin or similar liquid fills provide damping to improve accuracy and reduce pointer flutter, especially under vibration or impulse loads common in burner systems. It is built for non-corrosive test liquids and gases, enhancing durability in oil or air pressure scenarios.
Considerations: The smaller dial provides compact visibility while maintaining accuracy in tight spaces. The back-mount orientation is advantageous for dashboard-like panels or control consoles on portable heaters.
MEANLIN MEASURE 0~15Psi Heater Heavy Liquid Filled Gauge

This heavy liquid-filled 2.5″ dial gauge uses a 1/4″ NPT connection and lower mount configuration, making it suitable for torpedo heater installations that require robust damping and clear readings under vibration. The lower mount design accommodates conventional panel openings and aligns with common installation patterns for portable heaters. It emphasizes stability and precision across typical low-pressure ranges encountered in burner systems.
Practical notes: Ensure proper threading and seating to avoid leaks; verify that the gauge is compatible with the specific gas or air service in use and that the liquid fill type matches your environment’s temperature and vibration profile.
Irnyso Oil Burner Pumps Test Gauge

This gauge is designed to fit various heater models and pump configurations, with a back-mount setup and 1/8″ NPT mounting threads. It supports compatibility with multiple heater brands and models, including commonly used Desa, Reddy, and similar systems. It’s a practical option for measuring oil pressure in burner installations and can assist in diagnostics and performance checks during maintenance or setup.
Considerations: Confirm thread compatibility with your specific pump or burner assembly and ensure the measurement range aligns with your system’s operating pressure for accurate readings.
PIC Gauges TRI-RC-254R1.75-D Tridicator

The PIC Gauges tridicator combines dual pressure readings with a temperature option in a black steel case, offering a compact 2.5″ dial and 1/4″ male NPT connection. It is suitable for complex boiler or heater applications where monitoring multiple parameters in a single instrument is helpful. The included design supports a broader diagnostic view for performance and safety considerations in heater systems.
Notes: If using multiple readings, ensure the temperature probe is calibrated and the readings are interpreted in context with pressure data to avoid misinterpretation during startup or load changes.
SENCTRL 5000 Psi Glycerin Liquid Filled Gauge

This high-capacity gauge combines a 2.5″ dial with a 1/4″ NPT lower mount, suitable for robust testing and monitoring of higher pressure lines in more demanding heater setups. A 304 stainless steel case with glycerin filling reduces pointer flutter and protects internal components from vibration and pulsation, which is important when pressure surges occur or when operating equipment with dynamic loads. It supports dual-scale readings (psi and kPa) to broaden compatibility with different measurement standards.
MEANLIN MEASURE 0-160Psi Thermal Gauge

Designed for higher pressure monitoring and temperature compatibility, this 2.5″ dial thermal gauge covers a broad range up to 160 psi with 1/4″ NPT connections and lower mount installation. It’s suitable for boiler and heater systems where pressure and temperature relationships are critical. The device supports integration with thermal sensors and resettable pointers for quick status checks after shutdowns or maintenance operations.
Considerations: Ensure the thermal gauge is matched to your heater’s maximum operating temperature and that the interface with your control system accommodates both pressure and temperature data for accurate safety thresholds.
Buying Guide: Pressure Gauges for Torpedo Heaters
- Pressure range: Match the gauge range to your heater’s operating pressure. Low-range gauges (0-15 psi) are common for fuel lines and air circuits, while higher ranges (up to 160 psi) are used in some boiler or high-pressure systems.
- Dial size and readability: Larger dials (2.5″) offer easier reading from a distance, while smaller dials fit tight panels. Consider back or lower mount configurations based on your enclosure design.
- Wetted materials: Brass and stainless steel wetted parts improve corrosion resistance when testing water, oil, or other fluids. Liquid-filled gauges dampen movement and reduce flutter in vibration-prone environments.
- Mounting and threads: Ensure the NPT size (1/8″, 1/4″, etc.) matches your installation. Back, lower, or front mounting options impact accessibility and panel layout.
- Vibration and pulsation resistance: For torpedo heaters, gauges with glycerin or other liquid fills help stabilize readings and extend gauge life under dynamic loads.
- Accuracy and calibration: Look for gauges with a reasonable accuracy percentage across the operating range and consider calibration intervals for critical safety applications.
- Multi-parameter options: Tridicators or gauges with dual scales or integrated temperature readouts can simplify monitoring in complex systems, reducing the number of instruments needed.
- Compatibility: Verify compatibility with the fluids or gases in your system (air, water, oil, etc.) and confirm that the gauge’s materials won’t corrode under operating conditions.
