Accurate Inventory Measurement in Receiving Tanks

Accurate Inventory Measurement in Receiving Tanks

The safe, consistent, and reliable operation of a dairy facility begins at the receiving tanks. Since space is at a premium, efficiency is a must. Most of the insulated storage tanks that receive and chill the raw milk are narrow to conserve footprint and their heights vary with capacity requirements.

Facilities commonly track the level of milk in each tank with hydrostatic pressure measurements taken by hygienic and sanitary pressure transmitters. Typically placed at the lowest point on the tank’s exterior, the transmitter must accurately and reliably measure the level of the milk in the tank to aid inventory and production planning. The neck of the transmitter penetrates the tank insulation and must provide a flush surface to the tank’s interior wall.

Challenges

Tank level measurements must be simple and accurate in order to maintain the milk quality, reduce waste and clean-up costs, and enable facility profitability.

Achieving these goals can be difficult because accurate tank level measurements depend on pressure measurements, which are affected by swings in ambient and process temperatures. In addition, the distance between the transmitter’s sensor and the diaphragm at the process connection can hinder reliable and responsive measurements.

Each tank requires a pressure transmitter that provides the appropriate turndown ratio for its height. If tank heights vary, the facility might need to stock and maintain multiple pressure transmitters, thus reducing efficiency in facility operations.

Solution

To address issues with inventory expenses and purchasing complexity, customers choose Yokogawa’s 3-A certified EJA565E Pressure and Level Transmitter with its 10:1 turndown ratio for accurate measurements in a variety of tank heights and environments. In addition, as teams install the EJA565E transmitter, they reduce stocking issues because the transmitter offers a wide variety of sanitary process connections and can be directly installed to existing connection points on a tank.

During setup, users can rapidly zero the transmitter and establish the 100% range values with the transmitter’s backlit display and pushbutton interface.

Regardless of wide ambient temperature swings in day-to-day operation, the EJA565E transmitter obtains accurate and reliable measurements. It is enhanced with active temperature compensation that senses process temperatures and is less susceptible to ambient temperature changes.

Key Advantages

EJA565E

  • Exceptional accuracy and a 10:1 turndown range enable standardization on a single model, thus simplifying ERP systems and reducing equipment inventory
  • Active temperature compensation provides robust and stable level measurements for improved inventory control, product quality, and safety
  • Comprehensive selection of sanitary process connections simplifies installation, maintenance, and stocking
