They are mainly used in the shipbuilding industry. This level gauges are produced by Polish producers and are available in two versions: normal version marine version - WM CharacteristicA set of heads of glass tube level gauges consists of upper and lower head equipped with a drain. The heads can be made right (handle taps on the right) or the left. During mounting on the tank must be inserted between the heads (upper and lower) glass tube having an outer diameter of 20 mm. Glass tubes for 707 set, in accordance with the needs of the client installation, can be cut and bundled with the 707 set or separately, in addition to that set.  If the length of the glass tube exceeds 2.5 - 3 m, we suggest connect glass tubes using pipe connection fittings. This facilitates the transport of the glass tube to the customer and allows the creation of pipe of large lengths (e.g. 10 m). Pipe connection fittings should be screwed to the brackets (or tank wall) to ensure adequate rigidity of the entire structure. We also supply sealing elements for glass tube level gauges sets of type 707, which consists of teflon seals and brass washers (see here). The set enables effective sealing of a glass tube in a type 707 liquid level gauge head.

It is designed for external mounting on a tank and reliably indicates the liquid level inside the container according to the principle of communicating vessels. Type 460 is available in freely selectable lengths and can optionally be supplied with threaded or flanged connections. If the center distance between the valve axes exceeds 1500 mm, the pipe is divided into several sections that are stably connected together using spacers. A stuffing box seal made of PTFE inside the valves ensures a secure seal. In case of contamination or damage, the valve liquid level indicator can be safely disconnected from the container and emptied at the connection points using the integrated shut-off valves. Due to the sensitive glass tube, type 460 is delivered unassembled. When assembling – especially with flange connections – care must be taken to ensure that the connections are precisely aligned and not twisted against each other to ensure stress-free installation of the glass tube. To protect the glass tube from mechanical impacts during operation, an impact protection tube made of Plexiglas® is optionally available.

It is designed for external mounting on a tank and reliably indicates the liquid level inside the container according to the principle of communicating tubes. Type 461 is available in freely selectable lengths and is exclusively supplied with threaded connections. The maximum center distance between the valve axes is 1500 mm. A packing seal made of NBR inside the valves ensures a secure seal. In case of contamination or damage, the valve liquid level indicator can be safely separated and emptied from the container via the integrated shut-off valves at the connection points.

Standard size range Large diameter tubes are sometimes called cylinders. The standard sizes of borosilicate tubes are given below.Choose the right outer diameter (OD), available wall thickness (WT), the required length (L) and the number of pieces, and then place your order by e-mail or contact form. The tubes are made of borosilicate glass 3.3. Detailed information about dimensions and tolerances of the borosilicate tubes we offer is available on the manufacturer's website, SCHOTT AG. NOTE! The standard tube length is 1500 mm, but we can supply tubes of different lengths.
