Flow meter

Whether the customer has moved the parameters. If it is the signal line of the coil (D4 type is not), use a magnet against the base and slide it left and right to get an instantaneous flow. Ask the customer if there is a signal that is not present after repeatedly turning the meter head, […]

Fault point: Sensor Verification program. 1. flowmeter installation position is correct 2. Whether there are media covering the electrode 3. Whether the flowmeter is grounded Test results. 1. Replace the installation position 2. The electrode is covered 3. No grounding Treatment options: 1. 1. Replace the installation position. 2. Clean the electrodes regularly 3. Instruct

Fault point: no pipe running with flow indication Fault point: Converter Troubleshooting solution. Test whether the parameter setting of the flow zero correction FS is equal to 0 Test result. Example: FS = +002 The solution: Close the front and rear valves in the full pipe state, and calibrate the flow zero point through the

Fault point: Converter Test tool: Multimeter Checking solution. 1. The measurement range of the flowmeter is consistent with the user’s equipment 2. The user will remove the 4-20mA line, enter the converter parameter settings, find the current zero point correction, and current full correction, and press the enter key to enter the current zero point,

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

Pulse output meets the following conditions: high-level amplitude > 22V, low level amplitude < 0.8V, pulse frequency ≦ 3000Hz. Current load resistance <500Ω. The communication protocol format is MODBUS-RTU

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
