GENERAL SAFETY INSTRUCTIONS IMPORTANT: It is your responsibility to: Ensure that all equipment operators have access to adequate instructions • concerning safe operating and maintenance procedures. This product is not approved for use with petroleum products (diesel fuel, unleaded gasoline, jet fuel, kerosene, etc.), aromatic hydrocarbons or other incompatible chemicals.
GENERAL Two types of ultrasonic inserts are available with the UM Saddle meters. One type has circuits designed for use with battery power (Electronic option QUDSBAN1); the other type has circuits designed for use with external power (Electronic option QUC1LPN1). See the UM Ultrasonic Electronics manual (P/N 920901-05) included with the saddle meter for detailed electronics information and available electronic inserts.
INSTALLATION Step 1 – Drilling hole: It is recommended that the saddle/ultrasonic electronics not be located on the very top or very bottom of the pipe. Ideal performance can be achieved with the saddle mounted at 2 to 4 o’clock or 8 to 10 o’clock. Hole should also be drilled perpendicular to the pipe centerline and tangent to the curvature.

INSTALLATION (Continued) Place the marked sleeve back into saddle, engaging the threaded studs to the depth marked. Twist the bottom nuts upward to bottom of sleeve flange, replace the two nuts removed earlier and tighten all nuts with 7/16 wrench. See Figure 5. Figure 5 Step 4 –...
OPERATION Determining the K-factor: The K-factor value is needed to convert the ultrasonic insert’s output pulses into volume or rate data. The graphs located on the back of the Quick Start Guide show K-factor values for many versions of water lines. By knowing the line you are using or the inside diameter of the line, you can determine this value.
