Knauer Pump Azura Compact (P 2.1S)

Introduction

The Knauer Azura Compact pumps can be controlled via flowchem.

As for all flowchem devices, the virtual instrument can be instantiated via a configuration file that generates an openAPI endpoint.

Connection

Knauer pumps are originally designed to be used with HPLC instruments and they support ethernet communication. Moreover, they feature an autodiscover mechanism that makes it possible to automatically find the device IP address of a device given its hardware MAC address. This enables the use of the valves with dynamic addresses (i.e. with a DHCP server) which simplifies the setup procedure.

Configuration

Configuration sample showing all possible parameters:

[device.my-knauer-pump]  # This is the pump identifier
type = "AzuraCompactPump"
ip_address = "192.168.2.1"  # Only one of either ip_address or mac_address needs to be provided
mac_address = "00:11:22:33:44:55"  #  Only one of either ip_address or mac_address need to be provided
max_pressure = "10 bar"  # Optionally, a string with natural language specifying max pressure can be provided
min_pressure = "5 bar"  # Optionally, a string with natural language specifying min pressure can be provided

API methods

See the device API reference for a description of the available methods.

Device detection

Azura Compact pumps can be auto-detected via the flowchem-autodiscover command-line utility. After having installed flowchem, run flowchem-autodiscover to create a configuration stub with all the devices that can be auto-detected on your PC.
