Apply a small amount of o ring lubricant to the piston and work the piston up and down to lubricate the internal o ring (1009) located inside the piston body. If after a period of use there is a question of gauge and thermometer accuracy, the following checks should be performed on the unit: Warning: Operator must wear eye protection while operating this instrument. /Type /Catalog /Pages 1 0 R xref 0000017985 00000 n 4 23 << /Length 14029/Filter /FlateDecode >> trailer It's shown in my 1996 Zahm & Nagel Instruction Manual for QC as obsolete but parts available. endobj 0000018988 00000 n 0000018777 00000 n <> For additional details, refer to our Privacy Policy. 0000016790 00000 n Do not pull the handle out but allow the bottle pressure to force the piston out as the sample is shaken. 0000018186 00000 n This page was generated at 09:21 PM. Note: Before operating, cool the volume meter to the approximate temperature of the beer being tested. The needle can be re-set by removing the face cover and inserting a small screwdriver into the slotted brass screw located at the 5 oclock position of the gauge. >> /XObject << (1020-B). 0000018389 00000 n Remove the volume meter from the trycock on the tank. Equilibrium is achieved when, after shaking, the temperature and pressure remain constant. <]>> then unlock the plunger and shake for at least 20-30 sec. After the test has been completed, open both inlet and outlet valves (1020-B) and blow out the beer sample with pressure from the aspirator bulb (1042).

This should be done at frequent intervals as part of the routine maintenance of the instrument. That's a Zahm-Hartung Series 2000 volume meter. Do not allow your hands to touch the metal body of the volume meter when shaking as this will cause a rise in temperature of the beer. ), a dead weight tester or a digital test gauge. Turn the clamping device screw clockwise so that the clamping device gasket (1025) makes a tight seal between the try cock and clamping device assembly (1021). stream Do not use hot water, as it will damage the thermometer. 0000017332 00000 n Turn the piston handle (1007) counterclockwise to the release position. Vigorously shake the volume meter until equilibrium temperature and pressure is established and record the readings. 0000016925 00000 n zahm tester nagel << endobj The most accurate range of the gauge is the midrange, and the gauge should be calibrated to this area.

Rinse out any traces of beer from the aspirator bulb (1042) to prevent the check valve from sticking. We may share certain information about our users with our advertising and analytics partners. Note: the volume meter chart (1049) gives solubility of COgas in average beer, and will be found to give lower readings than charts based on solubility in water. i attach to sample valve with all valves closed and plunger locked in, fill meter up to 1 psi less than tank, open sample & valve into zahm. Before operating, cool the volume meter to the approximate temperature of the beer being tested. 0000015935 00000 n The Zahm SS-60 Volume Meter was developed to determine average COlevels of gas in tank stored beverages. Rinse the inside of the volume meter with water to remove any traces of beer. 0000001394 00000 n /I1 22 0 R/I2 23 0 R/I3 24 0 R/I4 25 0 R >> A zero zone is located on the gauge face and the needle may occupy any place in this zone and still be in calibration-do not attempt to calibrate the gauge back to this zone. 6 0 obj Operator must wear eye protection while operating this instrument. Pulling the handle out will result in damage to the gauge.

Apply a small amount of O ring lubricant to the piston (1005) and work the piston up and down to lubricate the internal piston O ring (1009). The gauge should be checked and calibrated using the Zahm & Nagel tester (. 0000018561 00000 n

Partially open the vent valve (1020-B) to reduce the false pressure reading and allow the gauge pressure to drop to approximately the equilibrium pressure expected in the test, and then close the vent valve (1020-B). The lightweight design reduces operator fatigue while the stainless steel construction increases strength and resists corrosion. /CropBox [ 0 0 595.26001 841.85999 ] Clicking login or register below will redirect you to ProBrewer.com to start your login there.

Open the top vent valve (1020-B) and establish counter pressure with aspirator bulb (1042) (or other convenient pressure source) up to the approximate counter pressure plus hydrostatic head pressure existing in the tank to be sampled and then close the top vent valve. A precise piston release mechanism eliminates bleeding off of the sample and the potential for human error. 0000019112 00000 n <> Open the inlet valve (1020-B) and then fully open the trycock. Hold the volume meter by the handles-if the volume meter is not equipped with handles hold it by the base shield (1003) and the neck shield (1004a). If this is your first visit, be sure to check out the.

Refer to the chart accompanying the instrument for the corresponding gas volumes. When the gauge pressure is steady, remove the aspirator bulb (1042) and partially open the top vent valve (1020-B) so that the pressure on the gauge drops about 1 psi. x}k%0l4|?aQ^]I`a>V=$wGdy2TdV|}f~}[(Pn.?7Vno_'[fcwo{r_~tfpxy&5{_F>;w-~mB9ces-^]45g:j3muo~]/k n~??v !F%pm^?!_+0t_;?g5ggCGF 8-#n$8Lqb_5RkDfRGQubTaTvzk^*A9>Ba 5%.G7u!i=;Ksw@Y']_fo_}<0Gf/g g yO7>Ska. they then recommend to "relieve the false pressure" by quickly opening and closing the zahms top valve. 0000000016 00000 n

Close the lower inlet valve (1020-B) and lock the expansion piston (1005) in the in position.
