Endress+Hauser - working with you every step of the way

Endress+Hauser is a major supplier of measurement instrumentation and inventory control systems for monitoring and controlling bulk liquids during processing, transportation and storage. At your terminal or tank farm, this includes design, production, installation and servicing of instrumentation, data acquisition and control systems. Endress+Hauser has the largest installed base of instrumentation throughout terminals and tank farms worldwide.

The loading, off loading and storage of liquids at port terminals require detailed information on quantities and mass. This requires the most accurate level, flow and pressure as well as temperature measurement. Endress+Hauser offers state-of-the-art level measurement instruments, such as highly accurate radar and servo technology. However, to reach standard volume or even to easily compare mass figures, temperature, crude oil density, strapping tables, expansion functions and more should be considered. An Endress+Hauser flow measurement system together with an Endress+Hauser tank gauging system allow you to manage and optimize your inventory.

Flow Measurement Solutions

Endress+Hauser offers flow measurement solutions for custody transfer in various applications within the oil and gas industry, including:

Offshore platformsFPSOsShip/truck/rail wagon loading and off loadingPipelinesWell servicing RefineriesGas plants

•••••••

The loading and off loading of a crude oil tanker or a refined products tanker involves a large transfer of high value. Consequently, a decrease in the uncertainty of only 0.1% results in huge savings and a short pay back time. Endress+Hauser’s Promass Coriolis mass flow meter allows you to enjoy these benefits by increasing the accuracy in your measurement.

The large size Promass makes it possible to replace older types of mechanical meters, such as turbines and positive displacement (PD) meters. Promass provides direct mass measurement and is independent of changes in density and viscosity. It is small in size, requiring only a small footprint. Additional support is only needed for its weight, making replacement very easy and limiting additional costs for installation.

Load the right massPromass provides a direct and highly accurate mass measurement for loading and off loading. This is due to the fact that all Endress+Hauser mass flow meters are calibrated on an accredited test rig with hydrocarbons that have the same characteristics as the hydrocarbons that are measured by the flow meters in customers’ applications. Promass is also calibrated and approved by NMi for bidirectional use, meaning that Promass can be used for loading and off loading in the same set up.

What are the benefits of Coriolis mass flow measurement?

Reduce time in the harborAs soon as the tanker enters the jetty, loading or off loading can begin. When finished, the mass measurement is immediately available and the customer can, in turn, immediately produce the “Bill of loading”. As a result, the amount of time the tanker is in the harbor is greatly reduced. Also, the faster the tanker leaves, the more hours available for other tankers at the harbor.

Reduce the number of claimsEvery loading contract includes a paragraph about the difference between onshore figures and tanker figures. Typically, a difference of only 0.3 % is acceptable. If the discrepancy is larger, the buyer can make a claim which can often delay payment.

None-stop, continuous operation – no need for reproving on siteIntegrated advanced diagnostics allow for constant monitoring of the long-term stability of the meter. For this reason, no on site proving station is required. When there’s a need for online proving, the Promass Coriolis, with high turn down of up to 1:1000, allows on-line proving with small size and affordable piston provers on site, even for high flow rates. A metering station with Coriolis requires no straight runs and no flow conditioner or strainer, allowing for minimum space requirements and maximum cost savings. The small size and weight requirements allow for a full size metering station with an integrated prover to be positioned even on a small size jetty. Therefore, bidirectional proving can be carried out during ship loading and off loading.

Life cycle cost savingsPromass Coriolis mass flow meters operate maintenance free. A flow metering station based on Promass involves absolutely no moving parts, thus no wear and tear and no maintenance required.

Sensor breakdown information and backup, drift alarm and corrosion monitoring avoids shut downs and ensures high process availability.

Flow computerSince the transfer of product is in volume, mass measurement must be converted to volume. a flow computer is used to caculate the GOV (gross observed volume) and GSV (gross standard volume) at standard conditions. The flow computer calculates these volumes from mass according to API standards.

Overfill protectionTo reduce costs and increase the level of safety at your facility, we offer you the Micropilot M radar and Liquiphant level switch for secondary overfill protection. The Micropilot M differs from the typical mechanical float switch because it is a continuous measurement solution that can be used on various tank types, including floating roof tanks. The Micropilot M offers you the benefit of continuous monitoring, allowing your operators to check the gauge status at any time and monitor the gauge’s operation for deviation from the primary level device. In addition, the Micropilot M only requires two-wire power, making it an easy replacement solution for overfill protection.

Liquiphant is a cost-effective solution for overfill protection and was the first level switch to receive SIL certification, an international standard for operational safety. Liquiphant is the perfect and proven retrofit for float switches with an installed base of approximately 1,500,000 units worldwide.
