ENRAF measurement systems

Solve the missions on storage plants administration:

  • Reserve resources stock-taking;
  • Operated swap;
  • Leakage fight and material balance.

ENRAF systems provide operative data access, including:

  • Exact facts on liquid level;
  • Product scope;
  • Product mass;

Temperature measurement systems

Innovative usage of thermosensitive elements together with high class master transducer contributes to realization of extremely accurate temperature measurements. Temperature measurements allow determining average temperature with 0,1оС error.

Multizone VITO thermometers are equipped with necessary certificates and meet Russian and international safety regulations for utilizing in danger zones.

ENRAF temperature measuring systems allow obtaining exact product average temperature values in reservoirs. Using (VITO) multiple-unit thermometer allows determining: product exact average temperature, air-steam mixture exact average temperature, temperature profiles.

Using the device in combination with intellectual radar level meter, servo level meter or as a component part of hydrostatic measurement systems allows obtaining exact information in real time, including the following: level of liquid product, commodity water/product partition level, volume, mass, signalization.

Using different communication protocols it is possible to transmit all measured/calculated data to centralized higher level control systems (DCS, SCADA, MIS etc.).

Hybrid stock reservoirs management system (HIMS) has best reference and is based on usage of exact hydrostatic pressure sensors together with level meters, offering such advantages as hydrostatic reservoir stock gauging (HTG), as well as systems based on level measurement by means of level meters.

 The following is used for reservoir resources measurement:

  • Industrial standard Communication protocols (HART, RS485, Modbus);
  • Exact and reliable pressure measurement method

HIMS system provides:

  • Firm date-line;
  • Possibility of introduction of amendments on temperature and regular errors of sensors;
  • High steadiness of equipment and armature to influence of storable liquid product (due to the use of corrosion-resistant material)
  • Enraf system's compatibility with various types of hydrostatic pressure sensors;
  • HIMS System is produced in modular execution and may be connected to earlier established servo level meters and to intellectual radar level meters without necessity of system's full reorganization;
  • Reservoirs overflow signalization.

HIMS system references:

HIMS ENRAF System gives the full information on reservoir stocks with extreme data accuracy in real time on following parameters:

  • mass (not more than ±0.5%);
  • Level (±1 mm);
  • Commodity water level or partition level;
  • Average density on controlled temperature (not more than ±0.5%)
  • Average product temperature (±0.1OC);
  • Common controlled object;
  • Common standard volume;
  • Average density at standard temperature.

Entis Pro and Entis XS software

High-efficiency universal Entis Pro reservoir resources management programs are intended for the enterprises with big tank farms (tens or hundreds of tanks); Entis XS is focused on average and small tank farms. Entis Pro and Entis XS serve a wide range of ENRAF field instrumentations, including:

  • Servo-motor level meters;
  • Radar level meters;
  • Mechanical measurements data reformers;
  • Hybrid stock reservoirs management system (HIMS);
  • Thermoelements for point and average temperature measures;
  • Modules of analogue signals input (for integrated transfer of analogue signals);
  • coupling field device of interface (for remote control of valves and pumps)

Entis Pro and Entis XS accept the data from field devices, calculate, and normalize the measured data and presents facts on reservoir stocks in a user-friendly format. The format can be defined by the user in the process of system adjustment according to concrete requirements. Systems scan up to 100 tanks less than for 10 seconds in real time and present general information on tank farm condition, reservoir groups, common storable products volume, detailed research of separate reservoirs in matrix format, as a bar chart or a graphical form.
