Channel drainage flowmeter common problems and solutions

Project Overview

Magnetic inductive flowmeter frequently asked questions

• 1、How to deal with the channel drainage flowmeter showing zero alarm? Answer: (1) Make the liquid filled pipeline to change the installation method or installation location. (2) Remove and clean the electrode.
• 2、In thunder and other shock voltage interference, electromagnetic flowmeter work is not normal how to deal with? Answer: (1) sensor connected to ground. (2) has been grounded, check to exclude poor grounding conditions.
• 3、What is the time limit for water estimation in the event of a malfunction of the water meter of a polymer-driven injection well? Answer:In the event of a malfunction of the water meter of a polymer-driven injection well, the time for water estimation should not exceed 24h.
• 4、How to correctly and reasonably select the magnetic inductive flowmeter? Answer: Magnetic inductive flowmeter selection, should consider the caliber and range, pressure, temperature, lining materials and electrode materials, site conditions and other five points.
• 5、Magnetic inductive flowmeter installation environment should be how to choose? Answer: (1) the installation should not be strong vibration. (2) should try to avoid equipment with a strong electromagnetic field (such as large motors, large transformers), etc.; (3) choose to facilitate maintenance, easy to move around.
• 6、Magnetic inductive flowmeter at the beginning of the operation display fluctuations of 10% or more is the cause of what? Answer: (1) Horizontal installation, the fluid does not fill the entire pipe. (2) There is a fault in the grounding.
• 7、What is the reason for the display of magnetic inductive flowmeter jumping in operation? Answer: (1) The electrode is completely covered or severely covered by insulating objects. (2) Leakage at the electrode, etc. reduces the insulation capability of the electrode to ground. (3) Pulsating flow.
• 8、Magnetic inductive flowmeter vertical installation, what are the requirements of the medium? Answer: (1) The direction of media flow should be from the bottom up. (2) After the transmitter to ensure that the measuring tube is full of media.
• 9、What is the principle on which the magnetic inductive flow meter for injection stations is made? Which parts it consists of? Answer:The magnetic inductive flowmeter applied in the injection station is made according to Faraday's electromagnetic induction principle. It consists of two parts: transmitter and converter.
• 10、What is the working principle of magnetic inductive flowmeter for injection station? Answer: The measured medium flows through the transmitter to generate inductive electromotive force, and then converted by the converter into 0-20mA or 4-20mA DC signal output.
• 11、What are the characteristics of magnetic inductive flow meter? Answer: (1) can accurately measure the flow rate, is a non-volumetric measurement instrument; (2) wider measurement range, fast response, small pressure loss. (3) The measured temperature, pressure, viscosity and flow state of the liquid on the meter display value has less impact.
• 12、What are the advantages of magnetic inductive flowmeter in the process of using? Answer: (1) the transmitter structure is simple and reliable, there is no moving parts and throttling parts, there will be no blockage, the fluid through no head loss; (2) not subject to the measured medium temperature, viscosity, density, pressure and other physical parameters of the impact of change; (3) range adjustment margin, up to 1:100; (4) no mechanical inertia, responsive, easy to use and maintain.
• 13、For the newly installed magnetic inductive flowmeter, how to determine the fault during operation? A: For the newly installed magnetic inductive flowmeter, the operation process can be based on the output current of the converter or digital display indicator to determine the fault.
• 14、Magnetic inductive flowmeter installation is completed, what should be checked before power? A: 1, check all the laying of the connection cable is good, there is no pass, short-circuit, insulation and other faults 2, explosion-proof magnetic inductive flowmeter must check the cable into the junction box and the box is sealed.
