Note: It is recommended to use Modbus protocol and phase out WP protocol.

★Note: 1. See the random wiring diagram for external start, stop, and reset functions.

2. The L802, L803, and L804 series can be switched with each other by setting the secondary parameters of the instrument. When measuring saturated steam, you can choose either pressure or temperature compensation.

3. If the user selects a specific curve compensation input (look-up table method), please provide the relevant technical parameters or density table when ordering.

Selection example: WP-L802-02-FAG-HL-T; WP-LS802-71-AAG-HL-W;

WP-LCS802-01-ANG-HL-P-W; WP-LC802-01-ANG-HL-P-T
