In many cases solenoid pumps are used in preference to peristaltic pumps, as the common perception is that peristaltic pumps need too much maintenance due to the requirement of changing the squeeze tube on a regular basis. With high load applications and aggressive chemicals, this may be true. However, a peristaltic pump offers distinct advantages…

The Siemens SITRANS F M MAG 5100 W is an electromagnetic flow sensor  for all water and wastewater applications, and is recognised by many water authorities as the best mag flow meter to monitor your trade waste water sent to sewer. In most cases, if you have a commercial operation and are sending water to…

Growers need consistent and reliable dosage, even when the volume of water in use is subject to fluctuation and varied pressure levels. However, traditional venturi dosing technologies rely on pressure stability to achieve dosage consistency and fail to fully deliver in these situations.  Water powered dosing pumps overcome these problems by using a system known…

Depending on what has fouled the probe, there are different methods to clean the probe. One can choose to clean the probe on a regular basis and calibrate [Which pH buffer solution should I use first when calibrating?], or only clean when the controller drifts out of calibration. There are various methods, however, the most…

pH Buffer solutions are required to calibrate a pH controller with a pH sensor (probe). The 3 most common pH buffer solutions are pH4, pH7 and pH10, and are usually a different colour to clearly distinguish between them. pH 4 is often red, pH7 green and pH10 blue. It is recommended to write the pH…
