ULTRA-E-F

PART-1 INTRODUCTION

General

It is the engineers and technicians' hope to measure the flow on the non-invasive pipeline

reliably. Series ULTRA-E-F are state-of–the-art universal transit-time ultrasonic flow meters,

fit to measure flow of full pipe line, providing a measuring system with unsurpassed accuracy,

versatility, ease of installation and dependability. Although designed primarily for cleaner

liquids, the flow meter is tolerant of liquids with the small amount of air bubbles or suspended

solids found in most industrial environments.

Principle ofmeasurement

The ULTRA-E-F ultrasonic flow meter is designed to measure the fluid velocity of liquid

within a closed pipe. The transducers are a non-invasive, clamp-on type, which will provide

benefits of non-fouling operation and easy installation.

The ULTRA-E-F transit time flow meter utilizes two transducers that function as both ultrasonic

transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a

specific distance from each other. The transducers can be mounted in V-method where the

sound transverses the pipe twice, or W-method where the sound transverses the pipe four times,

or in Z-method where the transducers are mounted on opposite sides of the pipe and the sound

crosses the pipe once. This selection of the mounting method depends on pipe and liquid

characteristics. The flow meter operates by alternately transmitting and receiving a frequency

modulated burst of sound energy between the two transducers and measuring the transit time

that it takes for sound to travel between the two transducers. The difference between the transit-

time is directly and exactly related to the velocity of the liquid in the pipe, as shown in Figure 1.

Features

Built-In large capacity memory and USB data download function. The downloaded data can

be opened by EXCELdirectly.

Clamp-On transducers are easy to install, non-invasive, cost effective, and require no pipe

cutting or processing interrupt. Since the transducers do not contact with the liquid, fouling

and maintenance areeliminated.

Insertion transducers are hot-tapped installation, no pipe line flow interrupted.

Apair of sensors can satisfy different materials , wide different pipe diameters

Clear, user-friendly menu selections make ULTRA-E-F series simple and convenient to use

4 Lines display, can display total flow, flow rate, velocity and meter run status. Parallel

operation of positive, negative and net flow totalizes.

U.S., British and Metric measurement units are available. Meanwhile, almost all-universal

measurement units worldwide may be selected to meet customer’s requirements.

The heat measurement by configuring with Pt1000 temperature sensors.

Remote operation by the wireless handheld operator. No matter the pipeline in high altitude

or underground, users can install or adjust the transducer more convenient. The

communication range is about 100 meters in free range space, and 10 meters in through-wall

distance. Compared to the short distance of Bluetooth, it is more convenient and practical.

This wireless handheld operator has wireless remote reading function and it also can

operate the meters instead of paneloperations.

ULTRA-E-F

PART-2 CLAMP-ON TRANSDUCER INSTALLATION

General

The transducers that are utilized by the Series ULTRA-E-F contain piezoelectric crystals for

transmitting and receiving ultrasound signals through walls of liquid piping systems. The

transducers are relatively simple and straight-forward to install, but spacing and alignment of

the transducers is critical to the system's accuracy and performance. Extra care should be taken

to ensure that these instructions are carefully executed.

Mounting of the clamp-on ultrasonic transit time transducers is comprised of three steps:

Selection of the optimum location on a piping system.

Entering the necessary parameters into the ULTRA-E-F keypad. (ULTRA-E-F will

calculate proper transducer spacing based on these entries (menu 25))

Pipe preparation and transducermounting.

MountingLocation

The first step in the installation process is the selection of an optimum location for the flow

measurement. For this to be done effectively, a basic knowledge of the piping system and its

plumbing is required.

An optimum location is defined as:

A piping system that is completely full of liquid when measurements are being taken. The

pipe may become completely empty during a process cycle - which will result in an error code

being displayed on the flow meter while the pipe is empty. Error codes will clear automatically

once the pipe is filled with liquid. It is not recommended to mount the transducers in an area

where the pipe may become partially filled. Partially filled pipes will cause erroneous and

unpredictable operation of the meter.

A piping system that contains lengths of straight pipe such as those described in Table

2.1. The optimum straight pipe diameter recommendations apply to pipes in both horizontal

and vertical orientation. The straight runs in Table 2.1 apply to liquid velocities that are

nominally 7 FPS [2.2 MPS]. As liquid velocity increases above this nominal rate, the

requirementfor straight pipe increases proportionally.

Mount the transducers in an area where they will not be inadvertently bumped or

disturbed during normal operation.

Avoid installations on downward flowing pipes unless adequate downstream head pressure

is present to overcome cavitations in the pipe.

TransducerSpacing

ULTRA-E-F transducers are clamped on the outside of a closed pipe at a specific distance

from each other. The transducers can be mounted in V-mode where the sound transverses the

pipe two times, W-mode where the sound transverses the pipe four times, or in Z-mode where

the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once.

W-mode provides the longest sound path length between the transducers - but the weakest

signal strength. Z-mode provides the strongest signal strength - but has the shortest sound path

length.
