The metering pump is a kind that can meet the needs of various strict technological processes. The flow of the metering pump can be steplessly adjusted within the range of 0-100%. The structural characteristics of metering pumps are used to transport liquids (especially corrosive liquids). Special displacement pump.
Metering pumps are also called quantitative pumps or proportional pumps. Metering pumps are reciprocating positive displacement pumps, which are used for accurate metering, and the stability accuracy of metering pumps is usually required to not exceed ±1%. With the continuous development of modern industry toward automated operation and remote automatic control, Advantages of metering pumps, such as strong matching and adaptable medium (liquid), are particularly outstanding.

What is API 675 hydrostatic test?
API 675 says that the metering pump has to be tested at 1.5 times the MAWP (Maximum Allowable Working pressure) but not less than 20psig (API 675 4.3.2.1)
How many types of dosing pump?
There is electronic pumps and mechanical pump. Electronic pumps are run using an electronic EPU assy. mainly used outdoors because it does not need to have open air passages to cool itself. Mechanical pumps need fans to cool them so outdoor use is not recommended. Then there are diaphragm pumps vs. peristaltic pumps. Diaphragm pumps pushes chemical through valves that open and close to force chemical into a pressurized water line. The peristaltic pumps push chemical through a tube that is being squeezed by rollers.
Why can't a pump be used to compress air?
A pump can be used to a certain extent, but due to the compressibility of gases they are not very effective.
Why concentric reducer is used in pump discharge?
The pump discharge reducer doesn't matter if it's concentric or eccentric. It's the pump SUCTION that needs to be an eccentric reducer that is always flat on top (F.O.T.) The eccentric reducer on the pump suction reduces pump cavatation (pump catching air).
What is induction pump?
Induction pump is a term used to describe any type of pump that depends on electromagnetic induction for its operation. These pumps are often used for liquid alkaline metals that are expected to reach temperatures between 800 and 1000 degrees Celsius.
What is the function of a metering pump?
The function of a metering pump is to exactly dose an amount of fluids of a specified amount of time and with a constant flow rate. These pumps are mainly used in chemical plants to keep the mixture constant.
What are differences between bump pump and metering pump?
A bump pump is used to manually prime a system by creating pressure to push fluid through, while a metering pump is designed to accurately and consistently dispense a precise volume of fluid at a set rate. Metering pumps are often used in applications where accurate dosing is critical, such as in chemical processing or water treatment. Bump pumps are more commonly used in situations where a quick prime is needed, such as in irrigation systems or small-scale fluid transfer operations.
What is the function of the metering device?
It is understood that the metering pump is a special volumetric pump that can meet various strict process requirements, and the flow can be steplessly adjusted in the range of 0-100%, which is used to transport liquids (especially corrosive liquids). Metering pumps are also called quantitative pumps or proportional pumps. Metering pumps are reciprocating positive displacement pumps, which are used for accurate metering. Usually, the stability accuracy of the metering pump is required to not exceed ±1%. With the continuous development of modern industry towards automatic operation and remote automatic control, the advantages of strong matching of metering pumps and wide range of media (liquids) are particularly outstanding.

How many metering modes are available on a Nikon D70 camera?
One can check in the Nikon D70 manual.There are three metering mode available on a Nikon D70 camera.Spot metering mode,Matrix metering mode and Center-weighted metering modes.
What is the Meaning of fiscal meter?
Fiscal metering is defined by the Metering Regulations as "Metering related to the purchase and sale and calculation of taxes" It is a measurement of product (usually Crude Oil) flowing through a pipeline or other such system and is used to determine payment or other charges due. The metering system is regularly checked for correct reading by comparison to International standards.

What does RTW audio metering do?
RTW audio metering devices are used to visually represent sound data that the device picks up. The data can then be used for many purposes, as the data will typically be more accurate than the human ear.
What is the narrow tube that is used as a metering device?
The narrow tube used as a metering device in refrigeration and air conditioning systems is called a capillary tube. It helps to regulate the flow of refrigerant into the evaporator coil to control the cooling process.
How does the metering valve work?
The metering valve delays the flow of brake fluid to the front wheel disc brake, so that the rear wheel drum brake can apply braking a little earlier. Contact Phone : +86-15625008015 What’app : 15625008015
