1 Basic Requirements
1.1 Scope and purpose
This section provides the following flow switch.
---definition;
---classification;
---characteristic;
---Product information;
--- Normal use, installation and transport conditions;
--- Structural and performance requirements;
--- Rated performance verification tests.
This section applies to the detection of gas, liquid or granular solids flow rate for flow switch. If the flow rate exceeds a preset flow switch,
The switch will change its output state.
The flow switch is independent, having a semiconductor switching element, is expected to access the exchange rated voltage not exceeding 250V, 50/60Hz, or
Does not exceed the circuit's DC to 300V.
And detecting explosive materials for use with and/or is located in an explosive place some additional measures necessary for the flow switch, this section does not
Specified.
This section does not apply to equipment with analog outputs.
