Measurement conditions & notes

The LE100 combines flow sensing, a Pt100 temperature sensor, a polysilicon pressure sensor, and signal processing electronics.
Flow, temperature, and pressure can be measured simultaneously.
Uses an ARM Cortex-M4 32-bit processor and a 24-bit ADC.
Adaptive variable-frequency excitation helps reduce power consumption.
The insert-molded PEEK liner and electrodes support operation under the specified negative-pressure conditions.
The flow body is designed for installation without straight pipe sections; follow the model installation instructions.
Configuration options include infrared remote control, a Bluetooth app, RS485, and IO-Link.
Applications include steelmaking, marine equipment, electronics, and industrial gas production.
