描述

Use

The UH50.. heating and cooling energy meter physically acquires energy consumption. The amount of heating or cooling energy is acquired separately and can be read out either on site or from a remote location. The device consists of a flow measuring section and processor unit. The processor unit can be equipped with different sensors, different types of power supply and communication modules. The UH50.. is used to measure the consumption of heat in district heating systems and blocks of flats. It is also suited to measure the consumption of cooling energy (cooling energy only or in combination with thermal energy), or volume flow in hydronic systems.
Restrictions
Do not use the UH50.. to measure potable water.
Also, the product is not suited for use in systems operating on water-glycol mixtures.

Functions

Ultrasonic measuring principle
The flow is acquired based on the non-wear ultrasonic measuring principle, which requires no moving parts.
The quantity of energy supplied to the consumer by the medium during a certain period of time is proportional to the temperature differential of flow and return and the volume flow passing through the meter.
The water volume is measured in the measuring tube by ultrasonic pulses which are transmitted in the direction of flow and against the direction of flow. Downstream, the time required by the pulses to travel from the transmitter to the receiver is reduced, upstream it is increased. The water volume is calculated based on the difference in runtime.
The flow and return temperatures are determined using platinum resistors.
The water volume as well as the temperature difference between the warmer and cooler side is multiplied using a heat coefficient and the product is integrated. The result, which is the consumed heating or cooling energy quantity, is registered and displayed in the physical units kWh/MWh or MJ/GJ; the volume in m^3.
Processor unit
The same standard electronics unit with a built-in service unit is used for all flow rates.
Optical communication interface
The meter is equipped with an optical communication interface, enabling the device to be read and configured on site with the help of the WZR-OP-USB optical read head and the UltraAssist software.
Self-diagnostics
The meter continuously performs self-diagnostics, allowing it to detect a number of mounting or device errors and to display them.
