XSL intelligent traffic display
- Product Description
-
This instrument uses a high-performance microprocessor chip to collect flow, temperature, and pressure signals. After signal amplification, non-linear correction, and coefficient calculation, the instantaneous and cumulative flow rate, as well as temperature and pressure, are displayed. Flow signals can be output in unit pulse, (4~20)mA, and RS485 modes. It can be used with various flow meters for the measurement of working volume flow, standard volume flow, and mass flow of various liquids, gases, and steam.
Main Features:
5-segment instrument coefficient, automatic non-linear correction;
Any small flow signal can be set for exclusion;
Automatic compensation for the temperature and pressure of the medium;
Internal settings and flow values are permanently saved during power failure.
With a backlit LCD screen, it can simultaneously display the instantaneous and cumulative flow rate of the medium;
Working volume flow, standard volume flow, and mass flow display can be selected;
High accuracy, good repeatability, high reliability;
