smithtek-node-red-meter
The meter node multi function node for:
A: Recording run hours. this could be a machine, device, pump,motor.
B: Totalizer that can convert pulses into totals.This could be a water flow meter, energy meter to name a few.
The package contains 3 modules .
Metering
Multiply
Reset
Installation
Using node red palette manager search for "Smithtek-node-red-meter" Or CMD npm install smithtek-node-red-meter
Configuration
Metering Node
- Data Store
Save to:
The data can be stored to persistent context. The data will remain after restarts for the period required. - Meter Type:
run Hours
totalizer
Signal start
You can select string,bool,number
to trigger the recorder
When in Run Hour mode
the value increments in seconds
. Additional nodes will be required to convert this to minutes or hours.
when in totalizer mode
the neter will multiply the incoming value by the setpoint value adjustable in the config properties.
Signal stop
You can select string,bool,number
stop the recorder
Configuration
Reset Node
connect the reset node
to the metering node
send any message to the reset node. This will clear the recorded values.
Configuration
Multiplier Node
When the metering node is configured to be a Totalizer
connect the multiplier node
to the metering node
Send a message payload with a number. this will overide the multiplier property setting.
Example : Your flow meter pulses once every 10
litres. you set the multiplier value to 10
.
Note
The record value can be save even node-red is restarted
Input
- Record time:
- reset signal: to reset
global/flow
variable to 0 - start signal: start record time
- stop signal: stop record time
- reset signal: to reset
- Record pulse:
- reset signal: to reset
global/flow
variable to 0 - set multiplier: to set multiplier value
- input pulse aka msg from physical hardware or upstream nodes.
- reset signal: to reset
Outputs
- Record time: When the node is recording time, it will send the output value every second.
- Record pulse: The Input message will throughput to the output.
