SBEM’s Ultrasonic 136 Series – Model 136 ULP is a high-performance, non-contact plastic level transmitter designed for accurate and reliable level measurement in various industrial and water management applications. Operating on the Time of Flight principle, the 136 ULP emits ultrasonic pulses that reflect from the material surface to calculate a level based on the return time. With a measurement range up to 15 meters, this lightweight transmitter supports a 4-20 mA output and offers both display and non-display versions to suit diverse operational needs. Its weatherproof, rugged ABS plastic housing, IP65/IP67 protection rating, and PP sensor material ensure long-term durability even in harsh environments. Ideal for wastewater treatment, coal washing, irrigation systems, and water distribution, the 136 ULP requires no site calibration and is unaffected by the physical properties of the measured material. Optional remote indicators and Modbus compatibility enhance integration into global industrial control systems, making it a cost-effective solution for level monitoring worldwide.
