Rotor Insertion Flow Meter RIM20
The RIM20 multivariable rotor insertion flow meter uses three primary detection elements to measure the mass flow of steam, liquids, and gases:
- Rotor speed sensor
- RTD temperature sensor
- Solid-state pressure transducer
Operating Principle:Rotor insertion flow meters measure the flow of liquid, gas, and steam by detecting the rotational frequency of the rotor blades. According to the laws of physics, the frequency at which the rotor rotates is directly proportional to the flow rate. Rotor insertion flow meters measure the flow rate by measuring the local velocity at a strategic position in the pipeline.
The RIM20 detects the frequency in the sensor head. The RIM20 calculates the average speed in the pipeline based on the local speed and other parameters such as fluid type, pipe size, and Reynolds number. The volumetric flow rate is then calculated from this.
RIM20 Range and Benefits:The RIM20-V provides a direct display of the volumetric flow rate. This is the most cost-effective solution for flow measurement of liquid in various applications, ranging from general water flow to measuring hydrocarbon fuel flow.
The RIM20-VT includes a precision 1000 O platinum RTD temperature sensor used for calculation and displaying compensated mass.
The RIM20-VTP offers the functionality of a flow computer in a compact device. This multivariable device includes temperature and pressure sensors for an immediate display of compensated mass flow of gases, liquids, and steam. The device not only has outputs for totalized mass and alarm settings but the adjustable electronics provide up to three analog 4-20 mA outputs for five process measurements, including volumetric flow rate, mass flow rate, pressure, temperature, and density.
The RIM20-EM version for energy measurements provides real-time calculations of the energy consumption of a production unit or process. The flow meter can be programmed to measure steam, hot water, or chilled water. The RIM20-VTP-EM flow meter monitors one side of the process (flow or return) and uses the input from a second, separate temperature sensor on the other side of the process to measure changes in energy. The energy unit can be set in BTU, Joule, calories, Watt-hours, Megawatt-hours, and Horsepower-hours. The local electronics or remote electronics display two temperatures, delta T, total mass, and total energy.
