System Configuration
• From single tank level measurement to the largest oil refinery application, Proservo is an integral part of tank
farm management solutions. A wide variety of data output protocols is available for seamless integration into
many commonly used systems.
• The primary example is Hauser’s revolutionary Tankvision, a scalable concept offering local tank
management for up to 225 tanks via Modbus, V1 or Whessomatic 550 protocols. Collected data is available
to DCS and other plant management systems via a Host Link.
• Other examples include Hauser’s legacy systems such as MDP V1 Interface, FuelsManager, Tank
Computers NRM571 and NRS57.
• Output protocols
•Modbus, RS485 or current loop
•V1 serial pulse
•Whessomatic 550
•HART
•Mark/Space

Major Application
The number of measuring functions and output options as well as the lightweight compact design enables
Proservo NMS 5/7 to be installed in a wide range of applications at minimal cost.
Petroleum Industry
From the production of oil to storage at an oil depot, there is a need to measure and manage a wide variety of
products. A remote tank gauging and inventory management system combined with Proservo NMS 5 and a
receiving computer is an ideal way to measure and control the contents of the tanks.
Chemical Industry
For this industry, a wide choice of materials is available for the construction of the wetted parts, to ensure
chemical compatibility and long life.
Food Industry
In the brewing and beverage industries, where large volume of water or water-based products are being
handled, it is essential to obtain a precise level measurement to establish low cost production. Proservo NMS
7 can be supplied with a built in CIP nozzle if required.
Power Plant
Fuel oil levels are major applications where precise measurement is required to ensure safe operation.
Operating Principle
The Proservo NMS 5/7 tank gauging system is based on the principle of displacement measurement.
A small displacer is accurately positioned in the liquid medium using a servo motor. The displacer is suspended
on a measuring wire which is wound onto a finely grooved drum housing within the instrument.
