Water conductivity meters to ensure process water quality

Level sensors in networked beer tanks The Internet of Things (IoT) starts with a sensor. From industrial to commercial to home automation applica tions, the IoT offers ‘smart’ solutions that help make life easier, improve and streamline processes, and receive information that was previously unavailable, or difficult to acquire, in good time. Smart solutions are highly individ ualised to the respective application, but always begin with an object and a sensor. A level measurement sensor with a remote transmitter offers a practical means of monitoring level and fill appli cations and identifying hazards. In pubs, for instance, an emptying beer tank could be potentially hazardous! In this example application, two Keller pressure sensors work at the core of the solution to measure the liquid level in the tank and send a warning message to the brewery – by e-mail via the GSM‑2* remote transmitter, the mobile phone network, and the internet. The brewery sends an automatic order proposal to the landlord, who simply has to confirm the order. This automated, smart, M2M (machine-to-machine) solution reduces stress for pub landlords and saves brewery drivers from emergency weekend deliveries. It Among the key benefits of the water conductivity me ters are the high level of accuracy they deliver and their reliability. The meters are calibrated to provide precise measurements across various conductivity levels and are designed to operate consistently in harsh industrial envi ronments. This reliability is crucial for ensuring the water used in industrial processes meets the required standards and does not cause issues or defects in the final product. Another benefit of the water conductivity meters is that they are easy to use and maintain. They are designed to be user friendly, with clear displays and simple controls. With their robust construction and durable components Water conductivity meters are essential for ensuring the quality of water used in industrial processes. In many cases, water is a critical component of the production process, and any impurities or contaminants can cause significant issues such as corrosion, scaling, and product quality problems. Prei Instrumentation, a South African company, specialises in high-quality water conductivity meters which are used in several industries to ensure the process water meets the required standards. Prei Instrumentation’s water conductivity meters are designed to measure the electrical conductivity of water. This measurement is directly related to the level of ions, or charged particles, in the water. Water with a higher concentration of ions will conduct electricity better than water with fewer ions. Therefore, by measuring the elec trical conductivity of water, the meters can provide an accurate indication of the level of dissolved solids and other impurities present in the water.

to withstand the rigours of industrial use, they require minimal maintenance. These factors also help to ensure the meters are used consistently and correctly, which is essential for accurate and reliable measurements. Prei Instrumentation’s water conductivity meters are used mainly in the food and beverage, pharmaceuti cals, and power generation industries. In the food and beverage industry, water conductivity meters ensure the water used in production is free from contaminants and meets the required standards for taste and safety. In the pharmaceuticals industry, the meters serve to ensure the water used in drug production is free from impurities that could affect the efficacy or safety of the final product. And in the power generation industry, they serve to en sure the water used in boilers and cooling systems is free from contaminants that can cause corrosion or scaling. In addition to ensuring the quality of water used in in dustrial processes, water conductivity meters can help to improve process efficiencies. By providing accurate and reliable water conductivity measurements, the meters help identify issues with water quality before they cause problems. For example, if water conductivity in a cooling system starts to increase, this could indicate scaling or fouling. Identifying this issue early means operators can investigate and take corrective action before the problem becomes more severe. This helps to minimise downtime and maintenance costs.
