Tank Gauge with LTD-level Temperature and Density Technologies

Two types of measurement methods are used for tank gauge with LTD-level temperature and density: volume or mass based. In a volume based system, level is measured. In a mass based system, the measurement of the hydrostatic pressure of the liquid column is used. The users choice should, therefore, be based on how product inventory is calculated and accounted via volume or weight.

Both methods provide a direct measurement of one factor in the inventory equation, level or pressure. However, bulk storage tanks tend to have large diameters, store products with varying densities that can stratify, and require consideration for high tank levels and overfill protection. A small change in level can make a big difference in accountable volumes (level x diameter), while stratification can lead to level changes that are undetectable by mass based systems.

Float and Tape Tank Gauge with LTD-level Temperature and Density

These instruments have been the liquid level measurement technique of the petroleum tank gauge with LTD-level temperature and density market for over 90 years due to their simplicity, reliability and cost.

Float and tape tank gauge solution consists of a 2500 ATG selected for the appropriate tank type. The instrument provides a measurement to +/- 4 mm accuracy and tank side display that is suitable for inventory management to API specifications. If control room integration and volumetric calculations are required, a 2920 FTT tank gauge transmitter is recommended with a 8500 STS for spot temperature measurement. The selection of the transmitter often depends on the required or existing field communications and protocols. The 2500 ATG/2920 FTTcombination is ATEX approved and is also able to provide optional contact outputs for triggering alarms or relays. If only an analog (4…20 mA) level output is required (without temperature) the 8200 COT can be used.

Top 10 advantages of Non-invasive Ultrasonic Level Gauge

1. Good versatility. Level gauge can measure all kinds of tanks, spherical tanks, vertical tanks, horizontal tanks, and other irregular tanks

2. Two-wire system. 24V DC power supply, lower power consumption, safer. Reduce wiring costs.

3. The sensor realizes non-contact or non-invasive measurements to improve the probe’s resistance to harsh process conditions.

4. Stm32 microcontroller technology embedded in the application makes precision a more accurate, more intelligent instrument.

5. Easy to install. Large installation space and other auxiliary facilities are not required. The level gauge is easy to install, maintain, and use.

6. It can not only display on site but also send a control signal to connect DCS or SIS system.

7. Strong adaptability, a wide range of applications. It is not affected by dielectric conductivity, dielectric constant, pressure, and so on, and has strong adaptability to the physical and chemical properties of the measured liquid.

8. Non-contact measurement. The ultrasonic transducer is installed at the bottom of the tank wall. The level gauge is not affected by the medium. No hole is needed.

9. There are no mechanically movable parts. Avoid mechanical failure, no wear, and tear, long service life, lightweight, maintenance-free.

10. Continuous measurement.

Advantages of level gauge & float switches

There are many advantages of water level controls, also known also level gauge, including:


Living in an age where we need to be more conscious of the energy that we use, a water level controller is ideal at saving power. Normally, regulating water levels can consume electricity and wastewater. However, with automatic controllers, the electricity usage is limited as well as less water needed to regulate supply.


A water level controller helps save money by limiting the waste of water and electricity. These devices accurately regulate how much energy is used to protect against any unnecessary water/electricity usage. Over time, the money saved is quite substantial.


Another notable advantage with these devices is that they regulate on their own. Eliminating manual operations with a timer switch, the frustrations of manual monitoring water tanks are minimized. Water levels are maintained at the appropriate levels thanks to the automatic operations of these devices.


On average, water pumps are used more during midday. A water level controller can maximize the water usage provided during midday while automatically lessening the water usage at night. This results in an appropriate level gauge of water at all times being maintained, while providing you with the maximum use of your water at the appropriate times.


Addressing the durability problems found in earlier designs, the solid-state electronics in the newer models help to eliminate them. Not only do they help to eliminate the durability issues, but they also create considerable savings of the life span of the unit with an advanced modular design. In order to minimize problem areas of these designs, the only moving parts are the relays. These relays are easily replaced and tested by any skilled operator or electrician while being an inexpensive part.


Proving to be less costly, over time, than the original float design for the ‘toilet tank’. The solid-state electronics are designed to minimize volt usage (less than 1 volt). This directly minimizes the mineral fouling, plating, rusting, and deterioration of probes, proving to be safer and more efficient. These factors extend the life span of the controllers significantly, which saves money and energy.


These new solid-state electronics and integrated electronics offer superior performance, hassle-free installation, and lower cost to operate over time when compared to the lifespan of the original design. For continuous monitoring, the integrated firmware and digital dry-contact circuitry easily and quickly connect to the automation systems of a building. Each function of the integrated electronics and relays use LED lights to offer operators the ability to visually scan them in order to verify proper operations.
