Gray copper-free aluminum liquid level sensor for recovery cylinders

Value Brand

Value Brand Liquid Level Sensor 4LZH4 .38 Lb

SKU CH-4NAE-F9G79

Monitors refrigerant levels in 4LZH2 and 4LZH3 recovery cylinders, weighing 0.38 lb

  • Monitors refrigerant levels for accurate recovery
  • Copper-free aluminium resists corrosion in HVAC systems
  • Lightweight at .38 Lb for easy cylinder mounting
  • Compatible with 4LZH2 and 4LZH3 recovery cylinders
  • Prop 65 listed for chemical safety awareness

Liquid Level Sensor for Recovery Cylinders

This sensor monitors liquid levels inside compatible recovery cylinders during HVAC service work. It is designed for use with 4LZH2 and 4LZH3 cylinder models. Technicians handling refrigerant recovery will find it fits directly into their existing workflow. The unit weighs 0.38 Lb when empty.

California Proposition 65 Compliance

The product carries a Proposition 65 warning for chemicals known to the State of California to cause cancer and reproductive harm. No thermal, noise or power-draw specifications are provided for this passive sensing component. It operates without an external power supply or moving parts that generate heat or sound.

Copper Free Aluminum Construction

The housing uses copper free aluminum, which reduces the risk of galvanic corrosion in refrigerant environments. Gray finish aids visual identification in a tool kit. No bundled software, calibration certificates or mounting accessories are mentioned in the supplied data.

Questions about this item

How do I install the liquid level sensor on a 4LZH2 or 4LZH3 recovery cylinder, and what step is often missed?

Thread the sensor into the designated port on the 4LZH2 or 4LZH3 recovery cylinder using the copper-free aluminum fitting; the step often missed is verifying the gray housing seats flush to prevent refrigerant leaks.

What maintenance or replacement will the liquid level sensor need over time?

The copper-free aluminum body resists corrosion, but the sensor should be inspected during each refrigerant recovery cycle for debris buildup or physical damage and replaced if the float mechanism sticks or readings become erratic.

What limit appears first when the liquid level sensor is used continuously during long recovery jobs?

The sensor's mechanical float mechanism can wear under sustained high-volume refrigerant flow, leading to slower response or sticking before the copper-free aluminum housing shows any degradation.
