New tank for oil field chemicals

This new tank is designed to carry a full range of oil field chemicals, and it comes with a working pressure of 2.67 bar and a test pressure of 4 bar.

The design has a reduced height and footprint through using more of the empty space in the frame. The lower height minimizes the need for anyone to climb on top of the tank for operational or maintenance reasons.

The 1,000 gal capacity tank has dished ends and measures 2,300 mm by 2,300 mm. The overall height is 1,815 mm, with dip and vent valves 1,600 mm from the floor. It has slotted fork-lifting pockets, which help minimize the chances of dropping incidents, the firm points out.

Because of the partially dished ends, it uses fewer external frame stiffeners than other square tanks currently on the market and is relatively light, the firm adds. It also has a provision for a dial-type level gauge to be installed.

It is constructed of stainless steel and is suited for use in a marine environment. The new tank’s height makes stacking plus working on top of the unit easier and safer, the company notes.

Sensor usable in extreme temperatures

A new extreme temperature version of the Rosemount 2130 vibrating fork liquid level switch is designed for use in temperatures of –94° to +500° F.

The new version has built-in fault monitoring/self-checking diagnostics, suiting it for a variety of uses.

The Rosemount 2130 level switch is already in use in high and low level alarm and pump control duties, the firm notes. The switch is simple and easy to use, reliable in a range of applications, and requires no on site calibration. Addition of the extreme temperature version allows site managers the possibility to standardize on the Rosemount 2130 across a range of process environments.

The Rosemount 2130 “heart-beat” LED gives an instant visual indication that the unit is operational. In addition, the built-in fault monitoring/self-diagnostics can detect any corrosion of the forks or any other internal or external damage or breaks in the internal electrical wiring, which triggers a warning LED and fail-safe handling of the load.
