10 Sentry Equipment Corp
Liquid Totalizer
The liquid totalizer is a Pelton-type microturbine meter designed for low ow rates in
water systems.
The totalizer can display ow rate, total volume and is resettable by the customer. The
instrument has an accuracy of ±3.0% of its full scale value, which is 500cc/min.
Installation
Lifting hazard. Use proper lifting techniques when handling this equipment.
The CPS sampler is designed to be portable to allow for sampling in numerous locations.
Select a location that provides adequate support, operator accessibility, close proximity
to the sample being analyzed, access to cooling water (if required) and access to a gravity
drain. Samples in excess of 131°F/55°C will require cooling. It is highly recommended that
the CPS sampler be installed in a high-pressure portion of the sample line to ensure the
sample ow rate meets the EPRI guidelines for representative sampling.
Standard Customer Connections
Sample Inlet: 1/4” Compression tting
Sample Outlet/Drain: 3/4” O.D. Tube Stub (SS) (See note below)
Cooling Water Inlet/Outlet (if installed): 3/4” Compression ttings
ÂNOTE
Since the liquid euent is at atmospheric pressure, the method of connection can be either soft
(using hose clamps provided by others) or rigid tubing.
Filter Replacement - Standard Filter Housing (Refer to Figure 3)
Verify that the pressure regulator is fully closed (turned fully counterclockwise), the bypass
ow control valve is fully closed, the sample inlet valve is fully closed and the lter inlet
isolation valve is fully closed.
Open the collection lter housing and remove the lter retainer and any lter papers. The
lter housing is opened by unscrewing the blue anodized retaining ring and removing the
upper body. No tools are necessary.
Re-install the upper body and retaining ring and hand tighten only. Because the seal is
made around the circumference of the housing and not the face, it is not necessary to
use extreme force to close the lter holder. When the lter holder is properly assembled
and tightened, the bottom edge of the retaining ring will be ush with the bottom of the
lower housing.
