2150EX Area Velocity Flow System Safety Information Labels Read all labels carefully before installing the equipment! The 2150EX and its components are clearly labeled with color and/or text so you know what can be located in a safe or haz- ardous area (see figure below). For example, on the label shown below, light blue is used to indicate the intrinsically safe end and yellow to indicate the non-protected end of the cable and con- nector. Example of Safe and Hazardous Area Labeling on RS232EX

2150EX Area Velocity Flow Module Section 1 Introduction 1.1.1 2150EX Area Velocity The 2150EX measures liquid level and average stream velocity, Flow System Overview and calculates the flow rate and total flow. The liquid level and velocity measurements are read from an attached Area Velocity AV Module (AV) Sensor that is placed in the flow stream. Flow rate calcula- tions are performed internally using the measured parameters from the AV Sensor. Additionally, the 2150EX can measure its input vo

2150EX Area Velocity Flow Module Section 1 Introduction Circuits internal to the module compare the frequencies of the sound waves and extract the difference. An increase or decrease in the frequency of the reflected wave indicates forward or reverse flow. The degree of change is proportional to the velocity of the flow stream. 1.1.4 Flow Rate Using measurements from the AV Sensor, the 2150EX can cal- culate the flow rate. Many different flow rate conversion methods are supported: � Area Veloci
