How to choose a wastewater treatment dosing flow meter?

Case introduction

1. Overview of the dosing flow meter

The dosing flow meter is an instrument used to measure the dosing flow rate in the sewage treatment system. It can accurately measure the flow of chemicals to ensure that the dosage of chemicals is reasonable and the enterprise can smoothly treat sewage.

2. Commonly used types of dosing flowmeters

1. Turbine flowmeter

Turbine flowmeter is a flowmeter that directly measures the volume flow of chemical liquid. It uses the principle of turbine rotation to measure the flow of liquid by calculating the rotational speed. This flowmeter is suitable for measuring low-viscosity liquids and gases in closed systems, and has the characteristics of fast response and high measurement accuracy.

2. Electromagnetic flowmeter

Electromagnetic flowmeter is a flowmeter based on Faraday's electromagnetic induction principle. It has a wide measuring range and is suitable for measuring various liquid media, including acids, alkalis, salts, etc. This flowmeter has the advantages of good linearity, high measurement accuracy and high reliability.

3. Ultrasonic flow meter

Ultrasonic flow meter is a non-contact flow meter. It uses an ultrasonic probe to measure fluid flow velocity without intervening in the fluid itself. This flowmeter is suitable for flow measurement when the liquid medium contains suspended solids, dirt, etc., and has the characteristics of easy installation and high sensitivity.

3. How to choose a dosing flowmeter

1. Definitions and parameters related to the flowmeter

When choosing a dosing flowmeter, you need to understand various The differences between flow meters include definitions, parameters, etc. For example, a flow meter needs to meet a certain flow range, accuracy requirements, etc. Determining these parameters will help determine the type of flow meter required.

2. User needs and operating environment

When selecting a flow meter, you need to consider the use environment and user needs. For example, users need to choose a flow meter that is corrosion-resistant and highly reliable; in an environment with magnetic interference, they need to choose a flow meter that is resistant to magnetic interference, etc.

3. Cost of use and maintainability

The cost of use and maintainability of the flow meter are also important factors in choosing a flow meter. For example, the price of electromagnetic flowmeter is relatively high, but the cost is low in long-term use; the price of turbine flowmeter is relatively low, but it requires higher maintenance cost.

IV. Summary

Sewage treatment dosing flow meter is an important equipment to ensure the smooth progress of sewage treatment. Reasonable selection of dosing flow meter can help enterprises reduce costs and improve production efficiency. When selecting a dosing flowmeter, you need to consider various parameters, operating environment, and usage costs in order to choose the appropriate type of flowmeter.
