Liquid Mist Monitor: LM 70 DGX







FilterSense liquid mist monitors are for detection and continuous monitoring of flowing, fine liquid droplets in pipes, ducts, stacks and small tubing. Applications include carryover detection with mist eliminators, process control for gas processing, emissions monitoring for scrubbers and other process liquid mist monitoring and detection.

Standard remote electronics provide easy access, while a passive sensor free of electronics ensures reliability and enables a wide range of sensor styles, mounting, process temperatures and pressures.

A high accuracy signal amplifier enables measuring very low levels of mist as well as fine micron droplets. Available outputs include relays, 4-20mA, Modbus and Ethernet. Automatic zero and span version is optional.

Principle of Operation

The LM 70 employs a field-proven combination of charge induction and protected-probe technologies invented by FilterSense. As liquid droplets flow near and around the probe, a minute current is induced. A DSP processes the signal into an absolute output relative to the amount of flowing mist. A protective layer over the probe works in combination with induction-sensing to ensure reliable operation. Maintenance is minimal. For durability, the sensors are passive and free of electronics. For safe, easy access and to facilitate instrument checks, the control unit and electronics are remote.
