Endress+Hauser EngyCal Btu and steam billing meters

Thursday, 28 April, 2011 | Supplied by: Endress+Hauser Australia Pty Ltd



The EngyCal RH33 Btu meter and RS33 steam meter provide high-precision data recording and billing information for custody transfer, steam measurement and energy-flow calculations for process and facility applications.

Both record energy data for billing purposes in applications such as custody transfer, heating and cooling systems, steam production and steam distribution systems. These meters also fit well in building automation applications such as district heating and cooling networks.

The Btu meter was developed especially for custody transfer applications with liquids such as water, water glycol mixtures or thermal oils. EngyCal RH33 calculates enthalpy (hot and cold), energy (thermal flow), density and mass flow based on the measured flow value and temperature differential. It is also available with custody transfer approval.

Calibrated and electronically paired temperature sensors ensure a high-accuracy temperature differential measurement, especially important in cooling applications. Its electronic sensor matching allows an exchange of individual sensors in the field. The cost-intensive use of paired sensors is no longer necessary; therefore, users will experience a reduction of costs in calibration and maintenance over the complete product lifetime. Temperature sensors will be shipped in a package with the preinstalled calculator on request. This reduces commissioning time and costs at the plant.

Typical applications include custody transfer and recording and billing the quantities of BTUs used in heating and cooling circuits and building automation systems.

The steam calculator can be used for recording and billing steam mass and energy flow for applications with saturated or superheated steam. It calculates the enthalpy and energy (thermal flow) as well as the density and the mass flow based on the measured flow value, temperature and/or pressure. All calculations are carried out according to the EN 1434 and IAPWS-IF 97 standard (International Association for the Properties of Water and Steam).

Typical applications include recording and billing steam energy consumption in food, chemical, pharmaceutical and power industries, as well as in building automation systems.

Both meters can be ordered with MID approval for custody transfer applications. Optional integrated differential pressure-flow compensation enables the highest possible precision.

The meters have a multi-line backlit LCD and support multiple operating languages. A simple and swift configuration can be carried out on the spot by using push-buttons, or by using the USB interface and Endress+Hauser’s FieldCare software. The integrated calibration logbook and the flexible user interface makes set up of EngyCal devices quick and easy, even for custody transfer applications.

Predefined universal inputs support simple and quick commissioning and are suitable for connection to and powering of all commonly used flow meters, pressure transducers and temperature sensors. The compact housing is suitable for direct field or wall mounting and DIN-rail mounting simplifies panel-mounted installations. This variety of mounting options makes the meters suitable for use in virtually any operating environment.
