Transparent consumption recording for liquid and steam applications.
Future-oriented companies invest to reduce operating costs through the efficient use of energy. In South Africa, these benefits are as pertinent as anywhere in the world given the current conditions in the electricity arena.
Liquids and steam
The BTU (British THermal Units) meter EngyCal RH33 and the steam meter EngyCal RS33 record energy consumption during the heating or cooling processes. The computers can be applied to support processes eg, steam production, heating, cooling and steam distribution systems, in district heating networks as well as in building management and other industrial applications.
The EngyCal RH33 was developed especially for applications with liquids, such as water, water glycol mixtures or thermal oils. EngyCal RH33 calculates the enthalpy, energy, density and the mass flow based on the flow value and the temperature difference measured.
Calibrated and electronically paired temperature sensors ensure a high-accuracy differential temperature measurement (primarily important in cooling applications) and make an exchange of individual sensors possible in the field (also on custody transfer devices). Cost-intensive use of paired sensors is therefore no longer necessary.
The EngyCal RS33 was developed for saturated as well as superheated steam applications and calculates enthalpy, energy as well as density and mass flow. All calculations are carried out according to the EN 1434 and IAPWS-IF 97 standard (International Association for the Properties of Water and Steam). Heat meters and temperature sensors can be ordered with optional custody transfer approval. As an addition, integrated DP-flow compensation can be provided for the highest precision in applications with difference pressure flowmeters.
Transparency and fault or alarm conditions
EngyCal has a built-in measurement as well as an event logbook. The measurement memory with defined report formats (day, month, year, billing date), event logbook and additional tariff counters create transparency during the regular process. Furthermore, a summary of consumption values is recorded for energy invoicing purposes.
Due to defined behaviour and the separate deficit counter the meter ensures transparency of energy calculations and documentation for invoicing. In steam applications, the wet steam alarm gives additional security as condensed steam hinders an exact energy calculation. Using the Field Data Manager Software the stored measurements, alarms, events and the device configuration can be selected and stored in an SQL database.
Open and web-based information and integration
If devices are connected using Ethernet, users can read out measurement data, calculated values and device data at any time using the integrated web server. Additional software for the supervision of online data is therefore not necessary. EngyCal can also be ordered with optional interfaces for Modbus RTU and TCP or M-bus in order to ensure easy system integration.
Units are equipped with a multiline backlit LCD display and a language package for free selection of operating dialect. Configuration can be performed using push buttons or via the USB interface using FieldCare.
Developed for the process industry
Pre-defined universal inputs support simple and quick commissioning and are suitable for connection to most commonly used flowmeters, pressure transducers and temperature measurement devices. The compact housing and versatile mounting arrangements make the use of this device possible in a variety of surroundings.
EngyCal products offer a simple standalone solution for steam and liquid heating or cooling applications that addresses energy savings and can be implemented quickly.
