Openchannel flow transmitter Introduction The LST400 is an ultrasonic level transmitter capa- ble of measuring liquid level or solid applications up to 15 m (50 ft.) or flow rates in all types of open channel flow applications. The transmitter has a single 4 to 20 mA DC analog output with HART 7 and five (5) relay outputs.

LST400 Ultrasonic Level / Open Channel Flow Transmitter The LST400 is an Ultrasonic Level Transmitter capable of measuring liquid l or solid applications up to 50 ft. / 15 meters or flow rates in all types of open channel flow applications. The transmitter has a single 4-20 mADC analog output with HART 7 and five (5) relay outputs.

ABB has decades of experience in flow measurement for the water industries. Based on a thorough understanding of industry requirements, innovative flow measurement products have been developed to control processes, increase profits and save costs. Highest precision in flow measurement is LST400 KM26 PGS100/

GAP technology found in LST400. The LST300 constantly monitors measurement data and optimizes the system for the best signal to noise at any tank size. This function ensures As is the case with all the other ABB ultrasonic and laser level instruments, there are no moving parts, so nothing ever wears out. LST300 is a maintenance-free device

ABB’s freedom of choice offers the right driver for the major fieldbus protocols suitable for ABB devices. The version matrix document shows for each protocol the software revision that’s compatible to the hardware and firmware revision of the device.

The LST400 is an ultrasonic level transmitter capa- ble of measuring liquid level or solid applications up to 15 m (50 ft.) or flow rates in all types of open channel flow applications. The transmitter has a single 4 to 20 mA DC analog output with HART 7 and five (5) relay outputs.

LST400 works on the non-contact principle of ultrasonics. A pulse of energy emits from the transducer at the speed of sound and is detected upon its return. The transmitter can distinguish the difference between a correct echo and other ambient noise.
