104 LOH

Industrial InstrumentationLevel

Description

SBEM’s Loss of Head Indicator-Transmitter 104-LOH is a reliable and efficient solution, designed for accurate differential head loss measurement in gravity filter beds, particularly in water treatment plants worldwide. Engineered with SBEM’s field-proven capacitance probe technology and powered by microprocessor-based electronics, the 104-LOH ensures consistent performance with minimal maintenance. It features a two-wire, loop-powered 4–20 mA transmitter, dual probes for high and low pressure points, and a user-friendly six-digit display with scalable output in mm or cm. Designed for ease of use, it requires only a zero and span setting—no full calibration needed onsite. Its robust weatherproof IP65 aluminium enclosure, PTFE-wrapped SS electrodes, and optional remote indicator enhance versatility in diverse environmental conditions. With high accuracy of ±2% of the electrode length, built-in surge protection, and full accessory support including stilling wells, valves, and mounting brackets, the 104-LOH is a complete, globally adaptable level control solution for efficient water management systems.
