Flow Gauge Part No. 9800-3100
The Flow Gauge is a portable measurement device that converts the pressure differential created by the Flow Finder into an accurate flow reading. Using a "quick connect" sampler assembly, the Flow Gauge attaches directly to the two sampler valves located on top of the Flow Finder.
It displays output in four color-coded flow ranges, corresponding to the output of the four original Flow Finder ranges (0–9.5, 0–19, 0–47.5 and 0–95 SCFH). Readings can also be taken on the higher range Flow Finder by simply multiplying the output of the complementary scale by 10 (for example, using the 0–19 SCFH scale for the 190 SCFH Flow Finder). A "times two" button on top of the gauge makes it possible to read flow rates up to twice the maximum rated flow range of the Flow Finder being read.
For detailed information about the Flow Gauge, refer to our
datasheet.

Flow Gauge Display Part No. 9800-3100
Reading the Flow Gauge is as simple as matching the color of the Flow Finder with the color on the face of the gauge. For example, a 0–47.5 SCFH Flow Finder has a blue label. Therefore, the blue scale on the Flow Gauge is used to determine the flow rate.
Please note that it is important to size the range of the Flow Finder for a particular installation with the expected flow rate. For example, you would not want to use a 0–47.5 SCFH Flow Finder where the flow rate is typically low. Looking at the scale above, you can see how it would be nearly impossible to read a flow rate of 2 or 3 SCFH on the blue scale. In this case, it would be better to install a 0–9.5 SCFH Flow Finder and use the green scale. With the gauge's times two capability, you could still read accurate flow rates with a 0–9.5 Flow Finder up to 19 SCFH.
Flow Direction Gauge Part No. 9800-3105
The Flow Direction Gauge is a manual air flow measurement device that provides both an accurate air flow reading and an indication of the direction of air flow. This information is used for leak locating in the Flow Bank System. The gauge is supplied with two quick-connect samplers (which greatly simplify the reading process), a carry strap and a case. The Flow Direction Gauge can be ordered with measurements in either Standard Cubic Feet per Hour (SCFH) or kilopascals (kPa). (Note: Unless specified the gauge is supplied in SCFH.)
Please refer to the Reference section for additional information about the Flow Direction Gauge, Flow Banks, and Flow Bank System.

datasheet for more information about the Flow Direction Gauge.

Flow Direction Gauge Display Part No. 9800-3105
As you can see the face of the Flow Direction Gauge consists of a normal scale and an expanded scale. When the gauge's needle points to the left, it indicates that air is flowing from the cable, into the Flow Bank and back out to a cable(s) through one of the other Flow Bank ports. The opposite is indicated when the needle is positioned to the right of zero. The rate of flow is indicated on the top scale, unless it exceeds 0.9 SCFH. When the needle is pegged to either side, pressing the "times two" button on the top of the gauge will allow you to read the flow rate indicated on the lower scale (up to 2.5 SCFH).
Digital Pressure Gauge (Part No. 9800-3123 / Part No. 9800-3135)
The Digital Pressure Gauge is a rugged, portable measurement device that reduces the potential for errors in readings by eliminating the parallax problems common with old-style C pressure gauges. The gauge face contains a four digit reading display that outputs in a variety of units including psi, mbars, kPa, in. Hg, etc. Each digit is displayed vividly in the output screen with the selected unit of measurement shown above the readout. Two versions of the gauge are available: 0–30 psi with over range protection to 60 psi (Part No. 9800-3123) and 0–100 psi with over range protection to 200 psi (Part No. 9800-3135). Reading accuracy is +/- 0.50% of full scale.
Power is supplied to the gauge by two AAA batteries, providing an average operating life of 2000 hours. To provide greater visibility in low light situations, the gauge includes a display backlight, which can be manually turned on and off. Other reading conveniences include peak and valley readings, auto-zeroing and measurement unit selection (
datasheet).

Notice the large output display. Each digit measures approximately .425 in (1.08 cm) high by .234 in (.59 cm) wide, and the unit of measurement is located in top right corner of the display. Located directly below the display are the four mode buttons: On, Zero, Units and P/V (peak / valley). These controls provide easy access to the gauge's features. A 60 minute auto shut-off is provided for gauge operations, and a two minute auto shut-off is provided for the illuminated display.
Digital Pressure Gauge with Tubing Part No. 9800-3123
The Digital Pressure Gauge is supplied with a 20 inch length of tubing and a standard tank valve secured to the protective rubber boot. The tank valve makes it possible to attach the air chuck for greater carrying and storage convenience. The total weight of the unit, including rubber boot, tubing and fittings is 18.23 oz (517 g).
To provide a quick reference for field use, the Digital Pressure Gauge is supplied with a laminated set of operating instructions. These instruction are attached to pressure tubing near the gauge face.
Flow Direction Gauge Components Part No. 9800-3105
The illustration above shows the components supplied with the Flow Direction Gauge. The gauge is housed in a protective rubber case with an adjustable carrying strap. Six feet (183 cm) of twin tubing connects the gauge to the two-port flow sampler. Quick-connect fittings are supplied on the flow samplers to ensure a leak-free connection when measuring flow direction at the Flow Bank. A "times two" button located on the top of thee gauge makes it possible to extend the reading range of the gauge, when necessary.
Direction of Flow Indicator Part No. 9800-3200
This extremely sensitive flow measurement tool provides flow direction information by responding to slight differences in pressure at two points on a cable system. It uses a light-weight styrofoam ball to indicate the direction of flow. Because it can detect pressure differences as small as .002 PSI, it is ideal for chasing flow in interlaced cables. It is also commonly used to check for leaks in cable plugs.
The Direction of Flow Indicator consists of a flow chamber encased in a clear plastic block. The block is equipped with plastic tubing on both ends. Threaded valve connectors provide a positive leak free connection.
Humidity / Temperature Meter Part No. 9800-3140
In applications where the measurement and monitoring of relative humidity and ambient temperature are desired, System Studies supplies a small, light-weight humidity/temperature meter. The meter measures temperature in the range of 14o to 122o F (-10o to 50o C) and relative humidity in the range of 5% to 95%. Readings are displayed as dual LCDs. The meter is provided with a plastic tube and air chuck for direct connection to pressure testing valve.
For more information about the Humidity / Temperature Meter, refer to our
datasheet.
Transducer Test Meter Part No. 9800-3600
This battery-powered, hand-held analog meter makes it possible to check the reading output of System Studies 4-20 milliamperes (mA) pressure and flow transducers. Two reading scales are provided: one for flow readings (SCFH) and one for pressure readings (PSI). A needle indicator provides the reference for determining the approximate output of the transducer. For flow devices the meter will indicate extended ranges as either 1.5x FS(full scale) or 2xFS. The meter housing measures 6.55 in (16.6 cm) long by 3 in (7.6 cm) wide by 3.35 in (8.5 cm) thick. It is supplied with two 3-foot (91.4 cm), 20-gauge test leads. Operating range is 0 to 150 degrees Fahrenheit (-17.78 to 65.56 Celsius).
