  * DESCRIPTION
- * Use this sensor to measure volume and flow of your house watermeter.
+ * Use this sensor to measure volume and flow of your house water meter.
  * You need to set the correct pulsefactor of your meter (pulses per m3).
  * The sensor starts by fetching current volume reading from gateway (VAR 1).
  * Reports both volume and flow back to gateway.
