measures depth. The optional surcharge velocity sensor (SVS) can be used to measure velocity during surcharge conditions. Surface velocity measurement The surface velocity of the water is measured with radar technology. A radar beam is transmitted from the sensor to the water surface at the center of the channel. Some of the signal is reflected back at a slightly different frequency. The differ ...

Explosion hazard. Trained personnel only must install or commission the equipment. Mechanical installation Site location guidelines For the best accuracy, install the sensor where the flow is not turbulent. The ideal location is in a long, straight channel or pipe. Outfalls, vertical drops, baffles, curves or junctions cause the velocity profile to become distorted. Where there are outfalls, vertical drops, baffles, curves or junct ...

W A R N I N G Explosion hazard. In hazardous locations, friction between surfaces can generate sparks that can cause an explosion. Make sure that no friction is possible between the instrument and any surrounding surfaces. C A U T I O N Potential hearing loss risk. Hearing protection required. The level transducer emits ultrasonic sound energy when powered. Ear protection must be worn when working within 1 meter of this device. Do not po ...

around the wall mount bracket. Refer to Figure 10. 2. Connect the clamp halves together with four bolts. Tighten the bolts sufficiently to temporarily hold the clamp in position. 3. Put the other two clamp halves around the front end of the frame. Refer to Figure 10. Note: Typically, the front of the frame will point toward the wall. Refer to Figure 10 and Figure 14 on page 16. If flow cond ...

• Examine the upstream and downstream flow characteristics. Use a mirror if necessary. Install the sensor above the water where the flow is stable. Do not install the sensor where there are standing waves, pools or objects or materials that can disrupt the flow profile. • If the upstream flow characteristics are acceptable, install the sensor on the upstream wall of the manhole ...

The sensor fits in the frame in only one direction and is held in position when the bail on the sensor is turned. Refer to Figure 12. The sensor can be removed from the frame and installed without entry into the manhole when the optional retrieval pole is used. 1. Make sure that the cable is tightly connected to the sensor. 2. Turn the bail to retract the locking bars on the sensor. 3. Put the sensor on the frame. Make sure ...

1 Spacer 2 Distance from interior crown of pipe to top of frame Align the sensor vertically – Flo-Dar with SVS The sensor must be aligned vertically to make sure that the sensor is above the flow under normal full flow conditions and that the SVS is activated under surcharge conditions. Item to collect: Ruler or tape measure 1. Measure directly above the crown of the pipe to the top of the frame. Refer to F ...
