Overview：

  Secondary instrument is the signal sampling tube 4 ~ 20mA signal processing into the relevant liquid level indication. The meter is equipped with 2 or 4 channels of high and low alarm which can be set by any programming on site. All parameters can be set online. The analog light column and 5 digits (including 1 symbol bit) are used to display the indicating liquid level.

  The signal sampling tube and the secondary instrument can be used independently, the users who adopting the 4～20mA signal input DCS system can use the signal sampling tube separately; The sampling signal device of the output for the two-wire system 4～20mA can also apply in the monitoring when switching on the secondary instrument. 

  Alarming output:Alarming output in two routes or four routes, dry contact(AC220V 3A), can set and memorize automatically

  Water level setting: the biggest preset range for water-level is ±3000mm

  Sampling range: The sampling range for the sampling tube is 6000mm. 

  Accuracy of the sampling: 10mm.

  Self-test function: It can display the fault of the secondary instrument component (mainly used for factory debugging).
