3010 Flow Transmitter Safety The equipment and this manual use symbols used to warn of Hazard Symbols hazards. The symbols are explained below. Hazard Symbols Warnings and Cautions The exclamation point within the triangle is a warning sign alerting you of important instructions in the instrument’s technical reference manual.
1.1 Manual Organization The purpose of this manual is to provide the information nec- essary to program, operate, maintain, and service the 3010 Flow Transmitter. To accomplish this, the manual is organized into five sections and an appendix. This first section is a general introduction to the flow transmitter.
Note Throughout this manual, we describe various accessories available for the 3010. We have listed the part numbers for all these items on an Accessory List, that you will find at the back of Appendix A Replacement Parts List. You can obtain part numbers for other Teledyne Isco equipment by calling the fac- tory.
Figure 1-2 Ultrasonic Level Sensor 1.3.1 SETUP Step The 3010 has a special feature to help you correctly align the ultrasonic level sensor. This Setup step lets you orient the ultra- sonic level sensor over the flow stream while an assistant watches the flow transmitter's display.
1.4 Controls, Indicators, Table 1-1 lists the controls, indicators, and terminal blocks for wiring to the 3010 Flow Meter, and briefly describes their func- and Terminal Blocks tions. Refer to Figure 1-3 for a view of the terminal blocks.
The technical specifications for the 3010 and ultrasonic level sensor (USLS) are listed below in Tables 1-2 and 1-3. Specifications Table 1-2 Technical Specifications for the Model 3010 Flow Transmitter Size (H x W x D) inches x 10 inches x 7 inches (38.7 cm x 27 cm x 18.7 cm)

If, after approximately four minutes, the flow transmitter cannot obtain a valid reading, the 3010 will show EE 80 on the display. In such instances, it may be necessary to realign the level sensor or check the operation of the flow transmitter.
Noise – Background noise can interfere with the operation of the flow transmitter. The unit must filter out this noise, or it may trigger on the noise rather than the returned echo. The 3010 uses a tuned circuit to filter out unwanted noise outside the operating frequency.
Wavelength – You can determine the wavelength of sound by dividing the velocity of the sound by the frequency. The frequency of the 3010 is about 49 kHz. You can find the length of a 49 kHz sound wave by dividing 1,125 feet /second by 49,000, which is 0.02296 feet or 0.276 inches.
FUNCTION KEYS – The yellow keys let you enter the program of the 3010 at specific steps so you can change selections or numerical values. These keys govern specific programming steps, and will be described elsewhere. Refer to Section 2.3.3 for the detailed descriptions of the Function Keys.
Overview stored in memory, even if it is only the default program installed at the factory. To program the 3010, press the yellow FUNCTION KEYS. The display will show the step number on the left and the number of the choice currently selected (or the numerical value entered for steps requiring a value) on the right.
3010 Flow Transmitter Section 2 Programming Note that you can do all programming for the 3010 in the shop, except for Setup (concerned with sensor alignment) and the Adjust Level step, which you must do at the job site after com- pleting the installation.

This is not only harmful to the 3010, but there is also the possibility of electric shock from the presence of AC power inside the unit. Always try to locate outside installations in relatively secure areas to min- imize the possibility of tampering or vandalism.
3010 Flow Transmitter Section 3 Installation Because it uses an ultrasonic level sensor, the 3010 does not have to be mounted directly above the primary device, or even close to the flow stream. You can install the flow transmitter at a conve- nient, protected location and run the cable to the level sensor.
A 15-amp breaker is sufficient. Do not attach the flow transmitter to a circuit that already has other equipment on it. Do not connect the 3010 to a circuit controlled by an unrestricted ordinary wall switch. 3.2.3 Voltage Selector Switch A slide switch above TS1 selects 120- or 240-volt operation.
It serves as a splice box between the level sensor and an extension cable. The extension cable then runs to the 3010. Extension cables of 25, 50, 100, and 250 feet (7.6, 15.2, 30.4, and 76.3 meters) are available from Teledyne Isco.
The flow transmitter works with any of the Teledyne Isco sam- plers. If you use the 3010 with an Isco sampler in a flow-paced sampling system, you must connect them together. You can...
Section 3 Installation Locations Greater Than 22 Feet – For distances between the flow meter and sampler greater than 22 feet, Teledyne Isco has a kit consisting of a 6-pin M/S connector that attaches to a cus- tomer-supplied cable. Follow the instructions supplied with the kit to attach the connector to your cable.
3010 Flow Transmitter Section 3 Installation 3.6 Safety Considerations While you will generally install the 3010 Flow Transmitter above ground in relatively safe environments, you may have to locate the level sensor in a sewer or manhole.

DEAD BAND: The nonuseable distance (2 feet) between the USLS and the liquid surface. This requires that at maximum level the liquid surface must be at least 2 feet from the level sensor. DISTANCE “D” is the distance from the USLS to the liquid surface. For the Model 3010, this can be from 2 to 12 feet.
4.1 High-Low Alarm Relay Teledyne Isco offers an alarm box that monitors flow rate infor- mation provided by the 3010 (see Figure 4-1). Relays trip when flow rate falls below or exceeds preset limits. High and low set points are user-selected and range from 0% to 99% in 1% incre- ments.
The High-Low Alarm Relay Box contains a microprocessor that Switches compares serial data from the 3010 to set values for high and low alarm trip-points for the relays. Rotary switches inside the alarm box set the trip points. There are two rotary switches for each limit.
Any color of wire or cable is acceptable, but make sure the connections end up the same as those shown. The maximum recommended distance between the 3010 and the alarm box is 250 feet (76 meters). The recommended wire gauge for interconnection cable is #18 AWG.
Devices a simplex serial output port providing ASCII level and flow rate data for remote transmission.
