Auto Zero ON with SWA 10 or Swema 3000md SWA 10 and Swema 3000md has an inbuilt zero valve. Auto Zero is set to ON by default. By the built in valve the zero pressure point is automatically checked every time you take a measurement by pressing ”ENTER”. - Page 8 Possible measuring modes: AP, AS and LOG. Radio/BlueTooth modem for balancing of ventilation SwemaTwin transfers measured values on the reference valve from one Swema 3000 to another through radio/BlueTooth modem or 40 meter cable. The flow relation between them is displayed, which makes adjustment according to the proportional method an easy task for just one person.

Insert k- factor, and the Swema 3000 calculates the air flow according to the formula: q = k sqrt(∆P). The specific k-factor is supplied by the manufacturer of (exhaust and supply) ventilation valves. -
Page 10: Measuring With Apf (Average Point Air Flow)
Measuring with APF (Average Point air Flow) Possible probes are: SWA 31, SWA 31E or SWA 07 or SWA 10 with pito static pipe or Swema 3000md. Use the APF mode for measuring the flow in ducts. Swema 3000 calculates the flow in l/s or m /h by multiplying the air velocity with the duct area. -

See Note Book. Please Note! If Swema 3000 with an inbuilt barometer and thermoelement is used. The displayed Avg, Max and Min va- lues are then calculated by the barometric pressure and tem- perature value at the different measuring points.

Page 13: Measuring With Dpf (Differential Pressure Air Flow)
Measuring with DPF (Differential Pressure air Flow) Possible probes with DPF are: SWA 07 or SWA 10 and Swema 3000md. See Differential pressure in the section The different probes for Swema 3000. The flow in the measurement of pressure drop across valves is directly obtained in l/s or m q = k sqrt (∆P) - Page 14 Use the calculation for k: k= 50/10 → 5,0 So the k factor in this case was 5,0. Set this in Swema 3000 to obtain the flow in l/s, m3/h or CFM. If the diagram does not extend to 100 Pa, select for...

(time constant + selected mea- suring time). Connect the flow capture hood and press ON. After a few seconds Swema 3000 is in measuring position. Choose mode by pressing the MENU1-KEY and move the marker to ”Mode” with the up/down arrow key. Press ENTER or SET and choose mode with the up/down arrow key. -
Page 16: Measuring With Bp (Back Pressure)
This can be corrected by using the Back Pressure mode. By measuring two times with SwemaFlow 125, with and without an extra throttle ring. Swema 3000 calculates the flow that reflects the true flow, with no capture interference. In the same way as AF mode the BP mode makes an average measure- ment over time. - Page 17 The display will also show point 1 & 2. Max is without the ring and Min is with the ring. Then you can choose if you want to clear or save your measurement. Swema AB Pepparvägen 27 SE-123 56 FARSTA ...

(g water / kg dry air) When all values are collected you can choose if you want to clear or save your measurement. -
Page 19: Measuring With As (Auto Sampling)
Sampling Rate is the time Swema 3000 uses to sample measured values, make an avarage and display the value. Swema 3000 uses a floating mean value, i.e. for example if a ”Sampling rate” of 30s is used, Swema 3000 sample a value 2 times/second during 30 seconds (60 values) and shows an avarage value of them. -
Page 20: Measuring With Asf (Auto Sampling Flow)
Measuring with ASF (Auto Sampling Flow) Possible probes with ASF are: SWA 31 or SWA 31E. Same as AS, but the Swema 3000 calculates the flow in l/s or /h. In ASF mode the area is not reduced by a k -factor. - Page 21 Start and stop measuring with the ENTER-button. Swema 3000 will collect values and calculate the average air flow and temperature. It will also calculate standard deviation, num- ber of measuring points and maximum and minimum air flow. When all values are collected you can choose if you want to clear or save your measurement.
