CAMLogic Vibrating Level Indicator GVL30 Series

Introduction – CAMLogic Vibrating Level Indicator GVL30 Series

The CAMLogic Vibrating Level Indicator GVL30 Series is a high-performance vibrating fork level switch engineered for accurate liquid level detection in tanks, vessels, and pipelines. Designed and manufactured in Italy, the GVL30 Series combines robust stainless-steel construction, universal electrical compatibility, and maintenance-free operation, making it ideal for demanding industrial environments.

Constructed with AISI 316L stainless steel wetted parts and a die-cast aluminium housing, the instrument offers exceptional corrosion resistance, ensuring long-term reliability even in harsh chemical or marine atmospheres. Its compact form factor and versatile mounting options—threaded or flanged—simplify installation and enable seamless integration into new or existing process lines.

The GVL30 operates on the principle of vibration frequency damping: when immersed in liquid, the resonance of its fork changes, triggering an immediate and reliable switching signal. With no moving parts and a fast response time of 0.5–2 seconds, the sensor provides accurate detection under a wide range of fluid viscosities—up to 10,000 mm²/s—without requiring calibration.

This series is an excellent choice for water treatment, chemical processing, food and beverage, and oil industries across the UAE and MENA region, where reliability, safety, and compliance are essential. Available from Dubai Sensor, the GVL30 delivers proven Italian precision for modern industrial automation systems.

FAQ – CAMLogic Vibrating Level Indicator GVL30 Series

Q1: What is the main function of the CAMLogic GVL30 Series?
A1: The GVL30 Series is a vibrating fork level indicator designed for reliable detection of liquid levels or flow presence in tanks and pipelines. It senses liquid contact by measuring changes in fork vibration frequency.

Q2: What types of liquids can the GVL30 detect?
A2: It is suitable for non-adhesive liquids with viscosities up to 10,000 mm²/s (centiStokes), including water, chemicals, oils, and food-grade fluids.

Q3: Is calibration required during installation?
A3: No calibration or adjustment is needed. The GVL30 is factory pre-set for immediate use after correct installation and wiring.

Q4: What are the power supply requirements?
A4: The device operates with a universal supply voltage — from 15–260V AC (50–60Hz) or 15–80V DC, making it compatible with most industrial systems.

Q5: How is the GVL30 installed?
A5: The unit can be mounted vertically or horizontally using threaded (G 3/4”) or flanged (DN25 PN6) process connections. The cable entry should face downward to prevent moisture ingress.

Q6: What is the difference between failsafe High and failsafe Low modes?
A6:

• Failsafe High (OFF position): Used for maximum level detection — relay de-energizes on alarm or power loss.
  
  
• Failsafe Low (ON position): Used for minimum level detection — relay energizes on alarm or power loss.
