Flow meters are classified into liquid flow meters and gas flow meters according to the medium. Then the common liquid flow meters mainly include: vortex flowmeter, turbine flowmeter, electromagnetic flowmeter, ultrasonic flowmeter, differential pressure flowmeter, open channel flowmeter, Coriolis mass flowmeter, etc.
Sino-Inst offers a variety of Liquid Flow Meters for flow measurement. If you have any questions, please contact our sales engineers.

Liquid Flow Meter Types
Water Flow Meter
Water flow meter is an instrument specially used to measure the flow of water in pipes. You can get many different types of water flow meters from your facility.
When used in certain applications, each flow meter has its own advantages. For many pipelines and similar systems, the water must be maintained at a specified flow rate to ensure the effective operation of the system.
At low flow rates, the speed of the water may be so low that suspended solids settle to the bottom of the pipe, which will deteriorate the efficiency of the pipe and eventually lead to the accumulation of contaminants, which can cause damage.
Since water flow meters can be used in a wide range of applications, there are many reasons to need these flow meters.
On the one hand, knowing that the fluid is in the right place at the right time is very beneficial to ensure that operating costs and efficiency are maintained.
These meters can also be used to ensure that fluids are kept in motion or to determine if the tank is properly balanced.
Any drop in the flow rate may indicate that the water quality is deteriorating and requires treatment.
In some applications, accurate flow measurement is critical to product quality and the health and safety of the final product. These meters are relatively easy to install in the pipeline, depending on the type of meter you choose.
Wastewater Flow Meter
Sewage flow, or wastewater can be a pain to accurately measure. The environment is corrosive and humid. While the flow itself can experience wide swings due inflow and infiltration. Wastewater is usually carried in non-full open channel pipes.
So, all the flow measurement instruments suitable for the Sewage flow are called Sewage flow meters, or wastewater flow meters.
Here you can find a Sewage flow meter to measure the flow of wastewater for your application.
How does a liquid flow meter work?
Liquid flow meter can be divided into the following categories according to the measurement principle:
Mechanics principles: instruments that fall into this category include differential pressure type and rotor type using Bernoulli’s theorem; impulse type and movable tube type using momentum theorem; direct mass type using Newton’s second law; using fluid momentum principle Target type; turbine type using the angular momentum theorem; vortex type and vortex type using the principle of fluid oscillation; pitot tube type using total static pressure difference, volume type, weir, trough type, etc.
Electrical principle: The instruments used for this kind of principle include electromagnetic, differential capacitive, inductive, strain resistance, etc.
Acoustic principle: There is an ultrasonic method for flow measurement using the acoustic principle. Acoustic (shock wave) etc. Thermal principle: There are calorimetric, direct calorimetry, indirect calorimetry, etc. that use the thermal principle to measure flow. Optical principle: laser type, photoelectric type, etc. are instruments of this type of principle. Principles of atomic physics: nuclear magnetic resonance, nuclear radiation, etc. are instruments that belong to this type of principle. Other principles: There are marking principles (tracing principles, nuclear magnetic resonance principles), related principles, etc.
What is a flow meter used for?
A meter that indicates the measured flow rate and/or the total amount of fluid in a selected time interval. Simply put, it is an instrument used to measure fluid flow in pipes or open channels.
Where should a flow meter be placed?
Most in-line flow meters are inline flow meters. They are all connected with the pipeline under test. Connect by flange, thread, etc.
The Insertion flowmeter is installed on the pipe under test by plug-in type. Suitable for larger pipe diameters.
Clamp-on flowmeter. The sensor is clamped outside the pipe for flow measurement.
How to choose a suitable liquid flow meter?
1.According to the process requirements, observe the on-site environment and determine the real need to install a flow meter on site.
2.After confirming the installation of the flow meter, it is necessary to understand the production process requirements and the various conditions of on-site installation in detail.
3.Analyze and determine each plan, fully understand the performance of the flowmeter specifications, and consider five factors according to performance requirements and instrument specifications, fluid characteristics, installation locations, environmental conditions and economics.
4.The performance of the flow meter is required for installation and measurement. After the measurement method is determined, select whether the meter needs instantaneous flow or cumulative flow in performance requirements, accuracy, repeatability, linearity, flow range and range, pressure loss, output signal characteristics and response Time and so on.
5.The instantaneous flow rate is still the cumulative amount. There are generally two types of measurement purposes: instantaneous flow rate and cumulative flow rate.
6.The requirements of measurement accuracy, how much is the overall measurement accuracy required?
