Description
The RMG TRZ03 series is an excellent representation of a proven and mature technology that is widely used throughout the natural gas industry due to its good price-performance ratio. The first generation was approved by PTB in 1993. Since then the meters have always exceeded the requirements of the relevant international standards.
The RMG TRZ03 is used both in the pipeline networks of the transport companies (TSOs) and in the transfer stations of the distribution network operators (DSOs) when high measuring accuracy for custody transfer operation, short inlet distances, robust and low-maintenance devices are required. In addition to the classic mechanical roller counter and the electrical pulse outputs, the meter can optionally be equipped with an encoder for serial transmission of the meter reading.
RMG TRZ 03 Turbine Flow Meter serves to calculate the flow rate of natural gas, butane, propane, nitrogen, air, acetylene, and other gaseous matters used in various technological processes (gas flow meter). It consists of the following components: body, measuring element (located on the body), and counting mechanism.
A flow straightener located upstream of the measuring element of RMG TRZ 03 Turbine Meter directs the gas onto the turbine blades. The turning number is proportionate to the average speed of movement of the operating environment and, therefore, to its flow.
The rotary motion generated by the turbine wheel is transmitted by a magnetic coupling to the meter head. Thereafter, the speed, which is proportional to the flow rate, is reduced by gearing and converted into the measured volume by choosing a needed pair of gear wheels. As a result, the obtained data is shown on the counting mechanism. High accuracy of measurements is ensured.
