good_gas_<type>_<variant>, good_gas_status, good_gas_contract_status, good_gas_internal_status

It’s gas flow accounted as eligible for recycling according to set of requirements.

types: sp, contract, internal

good_gas_status, good_gas_contract_status, good_gas_internal_status

Renders binary values where 1 means that flow fulfils the conditions and 0 means that it’s not good gas flow. If value or threshold is unavailable yield true for condition check.

conditions:

• oxygen test is defined as AN_200A_IN_RANGE = 1 or front_oxygen < front_oxygen_sp for last 40s
• moisture test is defined as AN_200C_IN_RANGE = 1 or AN_1000C_IN_RANGE or front_moisture < front_moisture_sp
• nitrogen test is defined as AN_200B_IN_RANGE = 1 or front_moisture < front_moisture_sp

for front metrics checks please refer to front metrics

formulas

Flow input for each variant is corresponding process_flow_from_customer_scfm_<variant>. Each variant has different condition. If condition is true then entire flow is treated as good gas flow.

HRS18006 ft_100 variant requires FT_100 > 100

good_gas_sp_<variant>

is equal to process_flow_from_customer_scfm_<variant> if and only if good_gas_status = 1

good_gas_contract_<variant>

Are defined same as sp type but front_*_sp are replaced by values from contract available at grafana dashboard. Moreover *_IN_RANGE are ignored. Base flow value is process_flow_from_customer_scfm_<variant>

good_gas_internal_<variant>

Implements checks as follows: front_* < max(front_*_sp, facility-contract-sp). Set of conditions are the same as for sp type.

all *_IN_RANGE sensors are logical test defined by ops team on site. They take precedence over front_ metrics checks
