The intelligent servo tank gauge Proservo NMS5 is used for high-precision level measurement in custody transfer and inventory control processes, enabling precise tank farm inventory management, loss control, cost savings and compliance with safe operation requirements.
Advantages
Liquid measurement accuracy of +/-0.7 mm
Can measure two interfaces between three liquids of different specific gravities.
Density profiling of the entire tank (tank profile) and the upper liquid (I/F profile)
Latest microtechnology design, simple shape, light weight and small size.
Wetted parts are completely separated from the electronic circuit.
Fitted with a 3" flange on the tank top, weighing only 12 kg (aluminum).
Various output signals including V1, RS 485, WM500, M/S, Enraf BPM and HART protocol.
Application
The Proservo NMS5/7 series intelligent tank gauges are used for high-precision level measurement in tanks and processes. They enable precise tank farm inventory management, loss control, cost savings and compliance with safe operation requirements.
Typical applications include: oil (fuel), LPG/LNG, chemicals, water/chemical interface measurement, food and liquid food, etc.
Intelligent tank farm installation makes the Proservo NMS5/7 series the ideal choice for single or multi-tank farm measurement tasks.
