  • Page 11: Bwt Meter Body

    Chapter 1. General Information BWT Meter Body BWT installations typically use a tilted-diameter meter body. A tilted-diameter meter body is so named because the transducers send their pulses at an angle across the diameter of the pipe. This type of meter body can be configured as a single-traverse or double-traverse installation.

  • Page 12: Double-Traverse Meter Body

    Chapter 1. General Information 1.4.2 Double-Traverse Meter Body A double-traverse configuration consists of two transducers mounted on the pipe so that the signal traverses the fluid two times before reaching the other transducer (see Figure 3 below). P = Distance that the signal travels through the liquid from one transducer to the other.

    Chapter 1. General Information Handling and Installing a Meter Body To ensure proper nozzle alignment, Panametrics uses the highest quality welding and machining techniques when manufacturing meter bodies. Since proper alignment of the nozzles is important to making accurate flow measurement, great care must be taken when unpacking and installing the meter body.

    Chapter 2. Standard Installation (FTPA Buffers) 2.5.2 Inserting the BWT Transducer Please read the following steps completely before beginning the installation of the BWT transducer. IMPORTANT: After you install the BWT transducers, you must allow the epoxy to cure for eight hours. Note: In gas applications, the typical minimum pressure should be 5 barg (75 psig) for the transducers to receive any signal.

  • Page 27: Verifying The Installation

    Chapter 2. Standard Installation (FTPA Buffers) CAUTION! Do not place insulation on or around the transducer or junction box. The transducer and junction box act as a heat sink that protects the transducer from high and low temperatures. After you install the FTPA Buffers and transducers, you must allow the epoxy to cure for eight hours. However, while the epoxy cures, you should verify that the transducer and buffer are working properly (see the next section).
