1. What kind of flowmeter needs a flow totalizer?

Answer: Non-intelligent flowmeter. The most basic feature is that there is no local display function, no integration, temperature and pressure compensation, alarm output and other functions. This flowmeter (to be exact, it should be called a flow sensor) needs a flow integrator.

2. What kind of flowmeter should the differential pressure transmitter be equipped with?

Answer: The differential pressure flow sensor (or throttling device) should be equipped with a differential pressure transmitter, which is named because its measuring principle is based on the pressure difference (differential pressure).

3. What kind of flowmeter needs temperature and pressure compensation?

Answer: Generally speaking, gas and water vapor are directly related to the temperature and pressure in the fluid pipeline because of their volume flow and mass flow, so it is generally necessary to compensate the temperature and pressure in order to measure accurately.

4. What is a pulse?

Answer: The pulse mentioned in the field of flow measuring instruments generally refers to the frequency pulse or volume pulse signal output by the flowmeter, which has a certain operational relationship with the fluid flow measured by the flowmeter.
