Swiss-Made Reliability in Water Detection & Level Control
H&H Level is excited to welcome Telma AG to our product portfolio. With over 40 years of experience, Telma develops highly reliable, Swiss-engineered systems for water leak detection, level monitoring, and control automation. From compact DIN rail modules to fully integrated alarm solutions – Telma delivers quality you can trust.
GL100 – Reliable Leak Detection
The GL100 is a compact, DIN rail-mountable leakage detector that works with external sensors (like the SKL400) to detect conductive liquids with high sensitivity. It’s ideal for early detection of water leaks in data centers, utility rooms, HVAC systems, or anywhere water damage needs to be avoided.
- Self-monitoring of sensor and controller
- Alarm relays for instant response
- Manual or automatic alarm reset
- Connect up to 100 meters of sensor cable
- Reliable water detection and protection against water damage
MUL-D Series – Programmable Level Control
Need precise level monitoring for tanks or process systems? The MUL-D2 and MUL-D4 transducers convert potentiometric signals into analog outputs (0–10V, 4–20mA), with 2 to 4 programmable relay outputs. These devices feature an LED display, tank linearization support, and flexible limit settings.
- For use with potentiometric level sensors
- Ideal for complex tank shapes
- DIN rail installation with easy configuration
- Sensor break detection and relay feedback
NL1750 / NL1751 – Simple, Smart Level Controllers
Looking for a no-fuss level switch? The NL17 series offers cost-effective level regulation for conductive liquids. Used in tanks, boilers, dishwashers, pools and more – these devices are perfect for overflow protection, dry-run prevention, or basic fill-level control.
- Compact and easy to install
- Configurable delay and sensitivity
- 230V or 24V power options
- Available for wet or dry contact logic
