Metal finishing for float balls is a special process used in float and tank applications. Finishing may require treating the exterior or interior of the float ball for a variety of purposes. A particular surface finish is necessary for a food environment. Weighted float balls may be necessary for specific gravity requirements when tanks have heavier liquids or more than one liquid in them. Magnets may be located within float balls to actuate float switches. There are numerous types of processes that require metal finishing for float balls. Here are several metal finishing methods offered by Arthur Harris and their intended applications. (more…)

The difference between NPT vs. BSP threads has more to do with where you live than their applications. Both NPT and BSP are pipe thread standards for screw threads used on pipes and pipe fittings to seal pipes.

BSP – UK, Europe, Asia, Australia, New Zealand and South Africa (most countries worldwide)

NPT – United States, Canada

Both threads have the same pitch and the familiar shaped peaks and valleys. However, the designs of the threads differ in two fundamental ways. With NPT, the peaks and valleys of the threads are flat. In BSP, they are rounded. Secondly, the NPT angle of the thread is 60 degrees and the BSP angle is 55 degrees. (more…)

What is a Float Switch?

A float switch is a sensor used to monitor a circuit within a tank as the level of a liquid rises or falls.  Types of float switches vary, but their general purpose is to activate pump control panels and any alarms if needed. The device has proven to be one of the most effective and reliable technologies to monitor liquid levels, and today float switches are utilized in a variety of industrial processes that require the monitoring of liquid levels stored within various types of chambers and tanks.

The color white, and more specifically, white colored cabinets, have never been more popular in today’s kitchens. White is always in style, regardless if you have a slick modern kitchen or relaxed country style. With their relaxed style and design flexibility, it’s no secret as to why white cabinets are a constant crowd pleaser. The color white can make a room look larger and timeless in one broad stroke. With white cabinets, hardware is the most crucial detail, as it is more than just an accent, Hardware completes the room and adds overall value to your kitchen. With all of the available options, selecting the perfect hardware for your white cabinets can be a frustrating exercise. Below we discuss what to consider when selecting hardware for white kitchen cabinets. (more…)

The working principle behind magnetic float level switches is to utilize a magnetic field to open or close a circuit as the level of a liquid within the chamber rises or falls. The stainless steel float within operates on the basic buoyancy principle that the force on a buoyant object is equal to the mass of liquid displaced by the object. Partially submerged within the liquid surface, the float moves within the chamber when the liquid level moves, thereby accurately tracking the liquid surface motion. (more…)
