Installation Instructions:

Install the calibration cylinder in the suction line
before the chemical metering pump. Ensure that the
cylinder is vertical and level. For Sealed and EZ­Clean configurations, two (2) isolating valves are
typically installed as per the drawing below. The top
of the cylinder should be vented back to the top of
the chemical container or to drain. The cylinder must
never be pressurized above 15 psi.

Caution! Max. cylinder pressure is 15 psi.

PVC CALIBRATION CYLINDERS

Installation & Operation Manual

Operating Instructions:

There are two (2) methods for using the calibration
cylinder, measuring volume or flow rate.

Method 1 – Volumetric. Any drawdown time may

be used: (Using the mL Scale)

1. Open isolating valves 1 and 2 to fill the cylinder to
the top mark on the scale (0 mL). Valve 3 is open
for venting.

2. Close isolating valve 1 from the tank on the suction
line. Leave isolating valves 2 and 3 on the
calibration cylinder open. Note the top needs to be
open to vent.

3. Turn on the chemical feed pump for a measured
drawdown time (seconds). Turn off the pump or
close valve 2 (first) and open valve 1 from the tank.
The volume displaced from the cylinder can be
read on the left side of the cylinder scale in mL. If
not starting at zero, subtract the starting reading
from the final reading.

4. To convert the mL reading into LPH or GPH use
one of the following two formulas:

LPH = 3.6 x [mL] ÷ Time (sec)
GPH = 0.951 x [mL] ÷ Time (sec)

5. If the reading is not the desired flow rate, adjust the
pump speed or stroke setting and repeat steps 1-4
until the correct flow rate is achieved.

6. Close valves 2 and 3 for normal system operation
and drain, or empty column.

Method 2 - Flow Rate, capacity based on 30 sec

drawdown time: (Using the USGPH scale)

1. Open isolating valves 1 and 2 to fill the cylinder to
the top mark on the scale (0 USGPH). Valve 3 is
open for venting.

2. Close isolating valve 1 from the tank on the suction
line. Leave isolating valves 2 and 3 on the
calibration cylinder open. Note the top needs to be
open to vent.

3. Turn on the chemical feed pump for 30 seconds.
Turn off the pump or close valve 2 (first) and open
valve 1 from the tank. The USGPH reading is on
the right side of the cylinder label. If not starting at
zero, subtract the starting reading from the final

reading.

4. If the reading is not the desired rate of flow adjust
the pump volume and repeat the process until the
correct rate of flow is achieved.

5. Close valves 2 and 3 for normal system operation
and drain, or empty column.

Description of models:

p

,

Sealed:

Top is glued to cylinder and contains a
vent or overflow connection. (FNPT).
Used in applications where there is a
positive suction head and a permanent
installation is desired.

Loose Cap: (Avail. up to 20,000 mL)
Top is loose and does not have a
connection in the top. Dust cover only.
Used in applications where there is no
positive suction head and the cylinder
must be filled from the top.

EZ-Clean: (Avail. 100 – 7000 mL
only)

Top is sealed with an O-ring and has a
vent connection, but removable for
easy cleaning. Used in applications
where frequent cleaning is required
such as polymer, alum, ferric chloride
or chlorine.
