Flow meter

Fault point: Converter Inspection tool: spanner / multimeter Checking program. 1. Check if the wiring between the meter head and the meter body is correct 2. Disconnect the meter head from the meter body and twist the two excitation wires of the converter together to see if the SYS alarm still exists 3. Check if […]

Fault point: Converter Test tool: Multimeter Solution: Remove IOUT and COMM wiring, use a multimeter to detect 4-20mA output between IOUT and COMM of the 4-20mA terminal of the converter Test result: 1. 4-20mA output 2. No 4-20mA output Solution: 1. Test the field wiring 2. Return the output module to the factory for repair

The nozzle flow meter is a differential pressure generation device for measuring flow, with a variety of differential pressure meters or differential pressure transmitters can measure the flow of various fluids in the pipeline. Standard nozzle throttling device with differential pressure transmitter can measure the flow of liquid, steam, and gas, widely used in petroleum,

Introduction Orifice plate flowmeter is a standard orifice plate and multi-reference differential pressure transmitter (or differential pressure transmitter, temperature transmitter and pressure transmitter) to form a high range ratio differential pressure flow device, can measure the flow of gas, steam, liquid and natural gas. Application Widely used in petroleum, chemical, metallurgy, electric power, heating, water

1. Energy measurement Energy sources are divided into primary energy sources (coal, crude oil, coal bed methane, LPG, and natural gas), secondary energy sources (electricity, coke, artificial gas, refined petroleum products, LPG, steam), and energy-carrying work substances (compressed air, oxygen, nitrogen, hydrogen, water). Energy metering is an important means of scientifically managing energy, achieving energy

1. Background Information Accurate monitoring of material flow in a wastewater treatment plant, as well as the use of the proper chemical cleaning agent mix, are required to meet both safety and regulatory requirements. A number of flow meters and solutions may be used to accomplish this. This study will cover the advantages and capabilities of

Are you responsible for the maintenance of an electromagnetic flow meter? Do you need help on how to calibrate a magnetic flow meter? If you do, then you must know that proper calibration is essential to ensure accurate readings. This blog post discusses the steps necessary to calibrate your flow meter properly, why it is

Do you need to measure the flow of liquids in your business but don’t know where to start? Do you need reliable flow measurements done regularly? If you answered yes to either of these questions, then you need to consider using an electromagnetic flow meter. An electromagnetic flow meter, also known as mag meter, is

An electromagnetic flowmeter uses the principle of electromagnetic induction through an applied magnetic field to measure the flow of conductive fluids through an electromotive force. Simply put, an electromagnetic flowmeter is an instrument used to measure the flow of fluid-like materials with conductive properties. Once calibrated by water, the electromagnetic flowmeter can measure the flow
