Product Water Flowmeter

TM 55-1905-223-24-7

r. Product Water Flowmeter. This flowmeter (7, FIGURE 1-6, Sheet 2) consists of a transparent flow tube mounted

in the control panel and connected by hoses to intercept the product water outflow from the RO modules. A float inside the

tube moves in response to changes in flow rate causing a line inscribed on the float to travel up or down the scale

inscribed on the tube. The graduations on the tube indicate 0 to 50 gallons per hour. Normal flow is 16.6 gph.

s. WATER MONITOR WM1 Label Plate. The WATER MONITOR WM1 label plate (8, FIGURE 1-6, Sheet 2) is

located as shown.

t. POWER SWITCH S1. Label Plate. The POWER SWITCH S1 label plate (9, FIGURE 1-6, Sheet 2) is located as

shown.

u. LOW PRESSURE GAGE PG1 Label Plate. The LOW PRESSURE GAGE PG1 label plate (10, FIGURE 1-6,

Sheet 2) is located as shown.

v. PRODUCT FLOWMETER FM2 Label Plate. The PRODUCT FLOWMETER FM2 label plate (11, FIGURE 1-6,

Sheet 2) is located as shown.

w. High Pressure Gauge and Bypass Valve. The high pressure gauge (13, FIGURE 1-6, Sheet 2) regulating valve.

The gauge reads zero to 1000 psi. Joined to the gauge is the high pressure bypass valve (not shown) which reroutes the

flow around the regulator. The bypass valve is operated manually by turning the pointer from label plate OPEN (15)

(pointer left) to label plate RO (16) (pointer up).

x. BRINE FLOWMETER FM1 Label Plate. The BRINE FLOWMETER FM1 label plate (12, FIGURE 1-6, Sheet 2) is

located as shown.

y. HI PRESSURE BYPASS Vl Label Plate. The HIGH PRESSURE BYPASS V1 valve label plate (14, FIGURE 1-6,

Sheet 2) is located as shown.

z. Brine Manifold Assembly. The brine manifold (FIGURE 1-7) is a two-chamber reservoir installed in the right front

on the watermaker deck plate. The manifold provides:

(1) A product water inlet, outlet, test probe, and test vessel for salinity sampling/monitoring.

(2) A brine chamber used for:

(a) Receiving diverted low quality product water.

(b) Receiving air/oil separator and micron filter bleed-off wastes.

(d) Receiving and discharge of brine concentrate out of RO modules.

aa. Salinity Probe. A salinity probe (FIGURE 1-7) is installed in the test chamber of the brine manifold to monitor

water conductivity. The probe has a threaded PVC body, sensor electrodes, and signal cabling to the water quality

monitor.
