Pipe dope MUST NOT CONTACT the plastic flowmeter body. Some pipe dope formulas will react adversely with Polysulfone. If a sealing material is necessary, use of Teflon tape is

recommended. Do not over-tighten the threads on the plastic

flowmeter body. Overtightening NPT pipe threads may cause fracturing of the plastic flowmeter body.

Piping on the inlet and outlet of the flowmeter must be aligned. Pay special attention to this

loads. Examples of loads include: Solenoid valves, warning lights and AC relay coils. The module can only switch loads that consume between 2.5 and 90 watts, or have 5000R to 150R impedance respectively. If the load draws less than 2.5 watts, a loading capacitor is required. The capacitor ’s value and connection is demonstrated in Figure 5. If the

load draws greater than 90 watts, a power relay is

necessary. Figs. 6 and 7 show typical relay connections. Wiring Configurations:

Conventional Connection: See Fig. 5

Note: See specifications to avoid damage to FET (transistor).

CAUTION: To protect the FET from damage due to inductive collapse, use a “catch” diode, as demonstrated in section 1 of wiring configurations, when switching inductive loads such as solenoids and relay coils. Connection of Terminal 1 directly to a voltage source will destroy the unit.
