Why is the total hardness measured with LHV?

The LHV series has been specially developed for total hardness measurement with analyzers from the LIMES series. The LIMES devices work purely as limit value monitors and continuously monitor whether a defined hardness limit value is exceeded or not reached.

Typical areas of application:

• Softening systems: Monitoring of the drain water after ion exchangers – immediate detection of resin breakthroughs.
• Boiler feed water: Ensure that the required residual hardness is maintained in order to avoid limescale deposits.
• Reverse osmosis systems: Continuous control of the permeate quality.
• Drinking water treatment: Automated quality assurance of water hardness.

The LIMES system offers a cost-effective solution for automatic hardness monitoring, which reliably issues an alarm as soon as a limit value is exceeded.

How does the Reagent work?

The LHV Reagents are liquid color reagents for automatic limit value monitoring with LIMES analyzers (LIMES Base, LIMES Plus). The device automatically takes a water sample, adds the Reagent and evaluates the color reaction.

In contrast to measuring range devices, the LIMES system does not provide exact measured values, but monitors whether the set limit value is adhered to. If the limit value is exceeded, an alarm is triggered – ideal for the reliable monitoring of water softening systems.

What is the carbonate value measured for?

The carbonate value (also known as the temporal value) describes the proportion of the water value that is caused by hydrogen carbonate ions (HCO₃-). Monitoring carbonate levels is crucial in many areas of water treatment:

• Cooling water systems: The carbonate values directly influence the lime-carbonic acid balance. Excessive values lead to lime precipitation in cooling towers and heat exchangers.
• Boiler feed water: Hydrogen carbonate decomposes to carbonate and CO₂ during heating, which leads to corrosion in the steam/condensate system.
• Swimming pool and bathing water: The carbonate value is an important parameter for the water balance according to Langelier or the LSI index.
• Drinking water: The carbonate content influences the taste and the tendency for limescale formation in pipes.

How does the Reagent work?

The C25 Reagents are liquid color reagents for fully automatic water analysis with SYCON analyzers. The SYCON device automatically takes a water sample, precisely doses the Reagent and measures the resulting coloration photometrically.

Depending on the device mode, the system operates as a limit value monitor (SYCON 2602) or as a measuring range device (SYCON 2702, 2802) with continuous measured value output.
