Link unveils new level indicator

The new unit, which builds on the success of the company’s standard level indicator, has a robust metal body and a display that clearly indicates when the liquid level is found. Using ultrasonic level detection allows a large number of cylinders to be tested rapidly and precisely without the need to dismantle them from the fire system. The unit is capable of detecting a large variety of extinguishing agents including NOVEC, CO2, FM200 and Halons.

Iain Christie, director, Link, told The Motorship: “The idea for the product came about from a discussion with a shipping company who had seen our non-intrinsically safe indicator and wanted something to use on their vessels for testing, which was involving 50 man hours and lengthy shutdowns, resulting in extra cost and lost time. They wanted a solution.”

For multi-banked cylinders, the complete kit has a bespoke extension rod allowing access to second and third row cylinders, while the sensors have a removable head allowing ease of cleaning for instrument maintenance.

The ULLC –IS is certified to Group II Category 2G Ex ib IIC T4 Gb, meaning it can be used for all Zone 1 areas. Link Instruments says it’s simple to use and requires no calibration, has been completely redesigned and, as with all Link Instrument products, is built in-house following stringent QA procedures and testing.

“We spent four years developing it and did a lot of pre-testing before it actually went out, including a NOVEC extinguishing medium test onboard a Shell tanker at Milford Haven, which had excellent results,” added Mr Christie.

The company’s testing area ensures that each instrument is tested against a range of cylinders containing different mediums before it’s released. Link also offers a free half-day training and certificate of competency in the use of the equipment at its headquarters in Petersfield, UK. By prior arrangement, it will also demonstrate the instrument and offer training anywhere in the world.

The unit is also delivered with a training DVD which illustrates the simple operation.

“The release is happening now, with sales just starting through the website. So far, we’ve had a very good reaction from the shipping and offshore industry,” Mr Christie told TMS.

So far, Tyco has expressed an interest, while Wilhelmsen Shipping Services is the latest major shipping company to make an order.
