Yes you can use a flow meter to measure your water pressure. They are available at any home improvement retailer.
No. Most water meters are of the positive displacement type. They meter actual volume, and are pressure independent. Also note that water flow and pressure are not the same thing. You can have high flow with low pressure, and also low flow with high pressure, depending on the size of the pipe and/or openings (such as valves) and the pressure.
The purpose of a flow meter is to measure the flow of either air or water. They allow one to measure the total volume of air or liquid flow and the rate of the flow.

No, a barometer measures pressure.
(to check the flow rate of water ... calculate the pressure drop
A chemical meter is a device that can be used for tasks such as monitoring and testing the flow rate or other variables associated with water or other fluids. When fluids interact with chemicals, the pressure and other factors can change; a chemical meter can help detect and measure changes in fluids.
Newton per square meter is a unit of pressure; cubicmeter per second is a measure of air flow. I don't think it makes sense to convert one to the other.
A sphygmomanometer is medical device that is used to measure the blood pressure of a person. It consists of a cuff that can be inflated to stop the blood flow and mercury meter or manometer that is used to measure the blood pressure. It is commonly used along with the stethoscope. It was invented by Samuel Siegfried Karl Ritter von Basch in 1881.

sfig-moh-mə-nom-i-tər A sphygmomanometer or blood pressure meter is a device used to measure blood pressure, composed of an inflatable cuff to restrict blood flow, and mechanical manometer to measure the pressure. It is always used in conjunction with a means to determine at what pressure blood flow is just starting, and at what pressure it is unimpeded. They are also used in conjunction with a stethoscope to ensure accuracy.
Use a good steam flow meter to know the actual steam flow per hour and use a good pressure indicator to measure the steam pressure. Normally these instruments that are used to measure and calibrate the process parameters are, higher accuracy and pre calibrated with certification, and accredited to authorized national laboratory.
