Description

ELECALL EHT Series Liquid Level Bar Graph Indicator is a high-precision digital display instrument with an accuracy of up to 0.5% FS. It combines a clear LED numerical display and high-brightness bar graph for intuitive real-time liquid level monitoring. It supports flexible settings for input signals, measurement range, alarms, and output modes.
The EHT series features a fully open user-setting interface, with zero-point and gain adjustment functions for measurement values, compensation, and transmitter output. It supports digital cold-junction compensation, password-protected parameters, and permanent data retention after power failure. Various communication methods can also be customized according to customer requirements.
Important: The EHT Series is a display and signal-processing instrument and cannot measure liquid level independently. A compatible liquid level transmitter is required to provide the level signal. For a complete liquid level monitoring solution, please purchase the EHT indicator together with a suitable liquid level transmitter.
