Jensprima Jepp Flumsys 20HA multi-channel hardness analyzer
Thread Content
The Lumsys 20HA multi-channel controller, when used in combination with the PACON 5000 online analyzer, enables automatic online monitoring of 2–6 water samples, generating 2–6 4–20mA signals; this significantly reduces the purchasing costs for customers. Measurement parameters:l Total hardness: 0.21 – 534 ppm CaCO3
l Total alkalinity: 5.4 – 401 ppm CaCO3
Applicable model: PACON 5000
Typical applications: process water, boiler water, drinking water, circulating water, cooling water
Product features:
l Based on the titration colorimetry principle, ensuring accurate and stable measurements
l Displays measurement values for 2–6 channels simultaneously
l Integrates automatically with the PACON 5000 for automatic cleaning and measurement
l Allows setting of measurement intervals (5–360 minutes) and flushing times
l Provides automatic system fault alerts as well as warnings for insufficient inlet water pressure
l Offers 2–6 isolated 4–20 mA outputs (depending on the selected channels)
l Channels can be switched on/off freely, preventing issues with one channel from affecting measurements in other channels
l Features RS485 Modbus RTU communication
l Has data storage functionality, with export to USB drives in Excel format possible
