Product Overview
HXWP-LK Series Flow Totalizer and Controller
Four-digit instantaneous flow and twelve-digit cumulative display
The HXWP-LED series flow totalizer and controller is suitable for the cumulative measurement and control of flow rates for various liquids, steam, natural gas, and common gases.
I. Main Features
1. The universal no‑jumper input technology enables each instrument to accommodate a wide range of thermocouple types simply and quickly through straightforward parameter settings, further enhancing its versatility and adaptability.
2. The automatic calculation of the flow coefficient K supports multiple input signal types and can be connected to various differential pressure, pressure, and frequency‑type flow sensors (such as vortex, turbine, and orifice plates), with a wide range of compensation options available, including temperature and pressure compensation.
3. Features an exceptionally wide display and measurement range, with the ability to switch between displaying temperature-compensated measurements, pressure-compensated measurements, flow measurements (differential pressure, frequency), and twelve-digit cumulative flow totals (0–999,999,999,999 digits). Cumulative values can be displayed with up to three decimal places (0.001), and internal instrument parameters can be configured to allow a maximum cumulative total of 999,999,999,999.99 × 100.
4. By employing the table‑lookup method for density compensation, highly accurate cumulative flow control can be achieved automatically for both superheated and saturated steam.
5. The instrument panel has been equipped with an additional set of LED status indicators, with each LED corresponding to a specific state to clarify the engineering significance of the associated display value, thereby facilitating user observation.

III. Product Lineup of the HXWP-LED Series Flow Totalizer and Display Controller
★ Input Type:
★ Note 1: The LK802, LK803, and LK804 series can be switched between one another by configuring the instrument’s secondary parameters.
★ Note 2: With the exception of the 0–20 mA and pulse–open-collector input signals, all other signal types can be freely reconfigured by setting the instrument’s secondary parameters.
★ If the user selects a specific curve compensation input method (lookup table approach), please provide the relevant technical parameters or density tables when placing the order.
★ Model example: ① HX-WP-LK802 -02-AAG-NN
Compensated input 4‑digit flow totalizer controller; flow input type: 4–20 mA; pressure compensation input type: 4–20 mA; temperature compensation input type: Pt100; 4–20 mA transmitter output; no alarm output.
