About Orifice Plate Flow Meter With Transducer

ORIFICE PLATE FLOW METER WITH TRANSDUCER

The orifice plate flow meter is installed in the water circuit of the trainer. The flow rate measurement is based on the differential pressure method.

The orifice plate narrows the cross-section in the tube. The constriction of the cross-section causes an increase in velocity which results in a measurable differential pressure. A transducer based on variable capacitance (diaphragm method) is used to measure the differential pressure. It is indicated on a display. Taking the orifice geometry into account, the flow rate can be calculated from the decrease in pressure using Bernoullis principle and the Continuity law.

FAQs of Orifice Plate Flow Meter With Transducer:

Q: How does the Orifice Plate Flow Meter with Transducer measure flow accurately across various fluids?

A: The device utilizes a precision-engineered orifice plate to create a differential pressure across the pipe, which the transducer then converts into a flow rate signal. This method, combined with stainless steel/alloy steel construction and digital signal output, ensures reliable and accurate measurement of water, oil, or chemical streams.

Q: What are the typical applications for this flow meter?

A: This flow meter is used extensively in industrial flow measurement, laboratory testing, process control, and wherever accurate flow monitoring of water, oil, or chemicals is required. Its semi-automatic operation and digital interface make it suitable for both onsite and experimental setups.

Q: When should the Orifice Plate Flow Meter with Transducer be chosen over other types?

A: Select this flow meter when high accuracy, a wide pressure (up to 40 bar) and temperature range (-20C to 120C), and compatibility with multiple fluids are essential. It is ideal for settings that demand robust construction, efficient operation, and analog output integration such as manufacturing plants and research labs.

Q: Where can this flow meter be installed optimally?

A: For best results, install the flow meter in a straight length of pipe to ensure uniform flow conditions, utilizing the flange mounting for secure attachment. Its IP65-rated enclosure allows installation in industrial areas with dust or splashing water, supporting both indoor and sheltered outdoor locations.

Q: What is the process for connecting and starting the Orifice Plate Flow Meter?

A: Simply bolt the meter onto a prepared DN25DN150 flanged pipeline, connect the 220V AC power supply, and wire the 4-20mA output to your monitoring system. Once powered, the digital display and transducer are ready for immediate flow measurement.

Q: How does this flow meter benefit industrial operations?

A: Its high measurement accuracy, rapid response (<1 s), and repeatable results (0.2%) ensure precise process control and data reliability. The sturdy materials and IP65 protection minimize maintenance, while the broad fluid compatibility maximizes versatility and return on investment.
