- Page 57 Transducers Standard and High Temperature Transducers for Remote Standard and Large Pipes INTRODUCTION This document explains how to install standard and high temperature transducers on standard and large pipes for remote transmitters. The transducers can be installed on vertical or horizontal pipes. The transducers are clamped on the outside of a closed pipe at a specific distance from each other.
- Page 58 Pre-Installation Requirements A full pipe is absolutely essential for making accurate flow measurements. The flow meter cannot determine if the pipe is full or not. If the pipe is partially full, the meter will over-report the amount of flow by the percentage of the pipe that is not filled with liquid or may not detect any flow.
- Page 59 Pre-Installation Requirements Select a Mounting Configuration The transducers can be mounted in these configurations: • W-Mount where the sound traverses the pipe four times. This mounting method produces the best relative travel time values but the weakest signal strength. It is most often used for measuring low flows in pipes of sizes at the lower end of the transducer range.

Scaled Mounting Rail Top View Side View Figure 5: Standard pipe applications Example of a Remote System with Large Pipes LZ and YZ transducers may also be advantageous on pipes between 4…24 inches if there are less quantifiable complicating aspects, such as sludge, tuberculation, scale, rubber liners, plastic liners, thick mortar, gas bubbles, suspended solids, emulsions, or pipes that are partially buried where a V-Mount is required or desired.
- Page 61 Installation INSTALLATION Mount the Transducers onto the Pipe V-Mount and W-Mount Configurations After selecting a mounting location and determining the proper transducer spacing, mount the transducers onto the pipe: 1. Clean the surface of the pipe. If the pipe has external corrosion or dirt, wire brush, sand or grind the mounting location until it is smooth and clean.
- Page 62 Installation Figure 9: Transducer positioning Mounting Rail System Installation for RZ Transducers For remote flow RZ transducers with outside diameters between 2…10 inches (50…250 mm), the rail mounting kit aids in installation and positioning of the transducers. Transducers slide on the rails, which have measurement markings that are viewable through the sight opening.
- Page 63 Installation 3. Slide the two transducer clamp brackets toward the center mark on the mounting rail. 4. Place the first transducer at the zero point on the scale. Slide the clamp over the transducer. Adjust the clamp and transducer so the notch in the clamp aligns with the zero on the scale. See Figure Align Notch to Zero Figure 12: Align to zero...
- Page 64 Installation Z-Mount Configuration On horizontal pipes, when Z-Mount is required, mount the transducers 180 radial degrees from one another and at least 45 degrees from the top-dead-center and bottom-dead-center of the pipe. See Figure 1 on page 2. Installation on larger pipes requires careful measurements of the linear and radial placement of the transducers. Failure to properly orient and place the transducers on the pipe may lead to weak signal strength and/or inaccurate readings.
- Page 65 Installation 10. Place a single bead of couplant, approximately 1/2 inch (12 mm) thick, on the flat face of the transducer. See Figure Couplant is provided with the transducers. Generally, a silicone-based grease is used as an acoustic couplant, but any good quality grease-like substance that is rated to not flow at the operating temperature of the pipe is acceptable.
- Page 66 Transducers Small Pipe Transit Time Transducers with Rail Mounting (UZ) INTRODUCTION This document explains how to install small pipe transit time ultrasonic transducers with a rail mounting. The transducers can be installed vertically or horizontally. For horizontal applications, install them on the side of the pipe. The small pipe transducers have integrated transmitter and receiver elements.

Flow Flow Flow Flow Flow Flow Figure 2: Piping configuration and transducer positioning The system will provide repeatable measurements on piping systems that do not meet these pipe diameter requirements, but the accuracy of the readings may be influenced.
- Page 68 Installation Procedure INSTALLATION PROCEDURE All moving parts are already mounted on the rail. One transducer is stationery, one is movable by loosening the thumbscrew and sliding it along the spacing scale. The small pipe transducers are adjustable for pipe sizes between 1/2…2 in. (15…50 mm). Do not attempt to mount the transducers onto a pipe that is either too large or too small for the transducer.
