Before choosing a flow sensor, there are 9 questions that need to be answered. Rotameter has many material options, such as 304 stainless steel, 316 stainless steel or PTFE lined material for corrosive liquid, such as chlorine gas. Technical Support It should be noted that for Equation (3-37) to be strictly true, the measurement conditions must satisfy the following assumptions: The ultrasonic wave carries information about the flow rate as it travels through a flowing fluid. Operates accurately down to 1/2 to 1 gallon per minute flow rate. So you want to measure the flow rate? According to Faradays law of electromagnetic induction, when the conductor in magnetic field movement cutting lines, commutation in the ends of the conductor is e, its direction to be determined by the right-hand rule, its size and the magnetic induction intensity of the magnetic field B, the length of the conductor in magnetic field and a conductor is directly proportional to the speed of movement of the u, if B, L, u three perpendicular to each other, then. Chinese, Questions? Chlorine gas is a simple gas and its chemical formula is Cl. But all flowmeters will eventually require some kind of maintenance. If the meter error is expressed in % AR, the absolute error remains constant at high or low flow rates. so the flow rate of the fluid can be detected by receiving the ultrasonic wave, which can be converted into flow. Also underutilized in the chemical industry are various flumes that measure the flow of partially full tubes and can pass large floating or settleable solids. Do you need rate measurement and/or totalization? Talk to an Engineer Toll-Free at 1-800-866-0200 (USA). When the accuracy of a flow meter is expressed in % CS or % FS units, the absolute error will rise as the measured flow rate decreases. Instantaneous Flow is the amount that passes through the effective section of closed pipeline or open channel in unit time. Looking for more information on our products. How does an open channel flow meter work? Thus, the volume flow of the pipeline is: It can be seen from the above equation that the volume flow qV has a linear relationship with the induced electromotive force E and the inner diameter of the measuring tube D, and is inversely proportional to the magnetic induction intensity B of the magnetic field, and has nothing to do with other physical parameters.

Plug into any 110V to 240V wall outlet, and when there is flow, the J-PRO-22 Metering Pump will instantly and accurately inject the precise amount of chlorine (or other chemicals) based on the flow rate of the water! . In other applications, repeatability may be more important than absolute accuracy. Pump easily mounts on the top of the tank or a wall. The answer seems to be to buy a flow meter. The dP meters were continuously drifting out of calibration and could not be relied upon to accurately signal the chlorine dispensing control system. The ultrasonic pulses pass through a tube from one sensor to the other, like a ferryman crossing a river. Defining fluid flow as the amount of fluid flowing through a given location seems simple enough any flow meter will suffice. The magnetic field is a uniformly distributed constant magnetic field; Axisymmetric distribution of the measured flow velocity; The conductivity of the tested liquid is uniform and isotropic.
