Reading measured values on tanks can be challenging because the measurement device is often difficult to access. This article discusses how RIA15 from Endress+Hauser can help in filling tanks and preventing tank overfill.

With the growing use of automation in the industry, collected data generally goes to process control rather than the field. So, how does a loop indicator help in solving challenges in hazardous areas?

For that, we need to explain what a hazardous area is. Well, these are areas like chemical plants where only explosive-proof instruments are equipped. In such areas, the RIA15, with its 8X approvals and international certificates, provides a safe and efficient level measurement.

The challenge of inventory monitoring

For inventory monitoring, you need parameters like level, temperature or pressure. From easy monitoring of tanks and silo levels to accurate custody-transfer tank gauging at tank farms (and even for fully automated systems), the operator needs to know about the plant status on site.

As mentioned before, the measurement device is often difficult to access. Moreover, in many cases sensors are installed in hazardous areas, which requires a specific design for the devices (ex-approvals).

Addressing risk management is also vital. For example, information on the level of the pipe and tank storage values are important to consider to avoid risk.

How does a Loop Indicator help?

The RIA15 loop-powered process indicator caters to such requirements. It has a very low voltage drop (<1V), compact housings and versatile installation options, and optimal readability, with the largest character size in a 96×48 mm housing.

In addition, it has bar graphs and physical units. Last but not least, as a competitive yet less expensive product in the market, the RIA15 makes a good fit in the industry.

In addition, displays in process hazardous areas intrinsically save inputs, for connection to zone 0, mounting in zone 1. The RIA15, with its superior approvals, helps in hazardous areas too.

The information provided by the RIA15

Is the pipe empty or full? Does it have the required temperature? The RIA15 loop indicator provides the information and lets you decide if you can open the pipe or not. It displays up to four HART values like level, temperature, pressure, and conductivity.

It also has operation status warnings and fits applications like inventory monitoring or tank level measurement in hazardous areas. The sensors can connect point to point (one sensor per RIA15) or in a multidrop mode (several sensors to one RIA15).

The display can install directly at the field equipment or up to a kilometer away. Either way, the staff always knows the status of the equipment and can act fast in case of unusual operation, safety risks, malfunction, etc.

Common applications

Filling vessels: You can fill a tank in the field. Through the radio connection in a control room, you can adjust the tank’s level measurement.

Preventing overfill: With the timely detection of the tank measurement, it helps in preventing overfill in the tanks.

Applications in smaller areas: The dairy industry, for instance, usually transports milk with trucks. Here, a RIA15 connected to these trucks can help get the right truck to the right tank and fill up the required amount.  

Setup of Micropilot FMR20

The RIA15 is a convenient tool for the basic setup (empty, full map) of the Micropilot FMR20 level measurement device. The FMR20 is used for the commissioning of many applications, like level measurement in the water and wastewater industry.

Additionally, you can also check out FMR50, a basic radar level measurement (Time-of-Flight) model for liquid applications.

Conclusion

With 8X approvals and risk management capabilities, RIA15 ensures proper filling of tanks and prevention of tank overfill. This leads to effective tank monitoring, even in hazardous areas.
