📡 LEVEL TRANSMITTER — One of the Most Important Instruments in Process Industries ⚙️
A Level Transmitter is used to continuously measure the level of liquids, slurry, or solids inside tanks and vessels and convert it into a standard signal like 4–20 mA for monitoring and control.
🔹 Common Features:
✅ Accurate level measurement
✅ 4–20 mA output signal
✅ HART communication support
✅ Suitable for liquid & solid applications
✅ Reliable industrial performance
🏭 Typical Applications:
• Water & Wastewater Treatment
• Chemical Plants
• Oil & Gas Industries
• Food & Beverage Plants
• Power Plants
💡 Important Point:
In most industrial transmitters:
➡️ 4 mA = 0% Level
➡️ 20 mA = 100% Level
This helps PLC/DCS systems monitor tank levels continuously and safely.
