Fuel Level Sender

The GLTV3 reed switch liquid level sensor uses a magnetic reed switch in the liquid level tube to measure

the liquid level. The rise and fall of the oil level will drive the rise and fall of the float, which will cause the 

signal of the internal circuit to change instantly. The performance of GLTV3 fuel level sender is stable and 

reliable. It uses a stainless steel probe rod, and the float material can be customized to stainless steel and 

plastic. Therefore, the GAMICOS GLTV3 oil level sensor is corrosion-resistant and wear-resistant, and is 

suitable for level measurement of oil, water and chemical media. We can also support the customization 

of probe rod materials for special media. The product can be connected to the oil gauge to realize zero and

 full position visualization and easy reading. It can support five-hole flange and threaded installation methods

, and 5 M5 screws are carried with the goods. We can also provide 1 year free warranty and technical support.

FAQs

1. What type of sensor is the GLTV3?
The GLTV3 is a reed switch-based liquid level sensor. It uses a magnet embedded in a float to actuate reed switches inside a sealed tube, providing accurate and reliable level measurement for various liquids.
2. What output signals does it support?
The GLTV3 offers multiple output options (customizable per application): Resistive output: 0~190 Ω or 240~33 Ω,
Current output: 0~20mA or standard industrial 4~20 mA
Voltage output: 0.5~4.5 VDC or 0~5 VDC
3. What are the measuring range and accuracy?
Measuring range: 100~2000 mm (custom ranges available)
Accuracy: ±10 to ±40 mm (depends on total length; higher precision available upon request)
4. What types of liquids can it measure?
The GLTV3 is suitable for a wide range of media, including:
Fuels: diesel, gasoline, alcohol
Water: potable water, wastewater, general-purpose water
Mild to moderately aggressive chemicals (material compatibility must be confirmed)
5. What materials are available for construction?
Stem (probe body):
L1: Stainless Steel 304
L2: Stainless Steel 316L (enhanced corrosion resistance)
Float options:
S1: Plastic: ideal for fuel/oil applications
S2: SS304: suitable for water and mild chemicals
S3: SS316: recommended for wastewater or corrosive environments
6. What are the IP rating and operating temperature?
IP Rating: IP67 (dust-tight and protected against temporary immersion)
Operating Temperature: -40°C to +85°C: suitable for harsh environments (e.g., trucks, marine, outdoor generators)
7. Does it support alarm functions?
Optional reed switch alarm contacts can be added:
H1: High-level alarm
H2: Low-level alarm
H3: No alarm (default)
8. What are the power requirements?
Supply Voltage: 10~32V DC (compatible with both 12V and 24V systems)
Power Consumption: 125 mW (low power design)
