Reflex Level Gauges

Reflex level gauges allow the medium to be viewed through a reflex glass: the side of the glass which is exposed to the medium has a prismatic surface, while the other side is smooth. The medium level inside the level gauge is indicated as the result of the light refraction principle, since the liquid filled area completely absorbs the rays of light and appears dark, whereas the rays of light are totally reflected in the gas/air filled area which appears bright.

Reflex level gauges offer great advantages in terms of low purchase and maintenance costs, as well as easy level reading. Anyway, they cannot be used in certain cases, for example when the separation level between two liquids has to be read, when the observation of the liquid colour is required or when the fluid to be measured is high-pressure water steam.

The Art of Servo Gauge

Servo tank gauges are a considerable improvement over the float driven instruments. They were developed during the 1950s. In this servo gauge, the float is replaced by a small displacer, suspended by a strong, flexible measuring wire. Instead of a spring-motor, servo gauges use an electrical servo motor to raise and lower the displacer.

Manual Gauging 8 displacer and controls the servo system. The motor also drives the integral transmitter. Mechanical friction in the servo system, transmitter, local indicator and alarm switches has no effect on the sensitivity and accuracy of the servo gauge. Also, turbulence has no direct effect. An integrator in the serve control system eliminates the effects of sudden product movements.

The servo gauge not only produces an average level measurement under turbulent conditions, but it also eliminates unnecessary movements and reduces wear and tear, greatly extending the operational life of the instrument.The original servo gauge does not look much like today’s modern version. The instruments have evolved into highly reliable mature products, and are gradually replacing mechanical float gauges, cutting down on maintenance and improving on inventory results.

Modern intelligent servo gauges have very few moving parts, resulting in long term reliability and accuracy. They also have a high degree of data processing power. The instruments do not merely measure the liquid level but are also capable measuring interface levels and product density. Accurate, programmable level alarms are standard. Accuracy’s of better than 1 mm (1/16 inch) over a 40 m (125 ft) range can be attained. The exceptional accuracy and reliability has resulted in the acceptance of the measurements and remote transmission, by Weights & Measures and Customs & Excise authorities in many countries.

Automatic tank gauge system advantages

The tank is a sealed space and we can’t see the liquid inside with eyes or simple measurement.

At this time we need a professional instrument to measure the liquid inside the tank. Secondly, there are a number of mobile tanks which need real-time monitoring of oil content in the tank, and the level of the instrument is very good to play a role in supervision.

With our tank gauge system, we can monitor the oil of the tank through the ultrasonic transmission data and the data will be transmitted to the database.

People can know about the information of the oil through PC or mobile terminal, which can manage and monitor the vehicle, preventing oil theft and oil leakage.

Other level gauges

Beyond the specific types of level gauges mentioned above, there are several other types of level gauges that exist. A common one is the fuel level gauge used to report the level of fuel in motor vehicles. Also, there are level gauges that rely on ultrasonic technology or guided wave radar to assess the level of fluids.

Compressed gas such as LNG and LP also have gauges that can be used to assess the amount of remaining gas available. Some of these rely on weight or sense the change in temperature on the tank surface where the vapor-liquid interface occurs.

Integrated tank terminal automation solution

We are selected refinery to design and implement its terminal automation system to cost-effectively enhance system reliability and availability for bitumen loading operations at the refinery’s Eastham Terminal.

The scalable, enterprise level midstream logistics management solution based on tank terminal automation software and DeltaV distributed control system (DCS) is helping the terminal achieve its goals of digitally transforming its operations and accelerating on a path toward top quartile performance.

Our previous system resulted in many operator interventions on a daily basis. Today, there are practically zero interventions due to the reliability of our new system, leading to a significant reduction in downtime and maintenance costs.

The accuracy and performance of tank terminal automation solution have also helped us maximise tanker load quantities and minimise the potential for safety incidents. As a result, loading delays that were commonplace are no longer a burden and our customer service levels have significantly improved.

Addressing critical system and asset availability issues requires modernisation, and our integrated solution is enabling optimisation. Operators can now access real-time inventory levels and other operational data on demand to minimise costly errors and delays.

Tank terminal automation solution includes TerminalManager software for management of terminal operations and commercial activities and the DeltaV DCS for accurate blending control and movement.

How To Choose A Tank Gauge for LPG LNG

What Is a Tank Gauge for LPG LNG?

A Tank Guages or tank level indicator is a piece of equipment used to measure the internal contents remaining in a tank (be it Diesel, AdBlue®, Petrol or other fluid). It gives a visual guide to the owner or user showing the remaining contents of a tank either digitally or via an analogue clock face.

a Few Things To Remember

A few things need to be taken into account when choosing which tank gauge for LPG LNG is suitable for you:

  • How large is the tank you are going to use the gauge for? (The larger the tank the more accurate you want the gauge to be)
  • How much are you looking to spend?
  • Are you looking to have it powered by a battery, the mains, or not at all?

What Types are Avaliable?

Float/Cat Tank Gauges for LPG LNG

A Float/Cat & Mouse tank gauge for LPG LNG is the simplest form of measuring the internal contents of a tank. They generally mount directly into the top of a tank, with the float mechanism situated directly underneath. This type of gauge provides a simple indication of tank contents. They generally have an analogue screen and are a fairly simple, yet effective way of measuring fuel levels. This style of gauge gives an approximation of the tank contents. They are a relatively cheap option but they are not particularly accurate.
