Datamatic has released the RSV™ Remote Shutoff Valve, a radio-frequency operated valve for disconnecting and reconnecting water services. The valve can be integrated into the company’s MOSAIC mesh network automated meter reading system. The ability to disconnect and reconnect service remotely can eliminate two field service calls each time they are used. Theft from inactive services can be virtually eliminated. In most cases, disconnection also expedites customer payment and simplifies collection. The RSVs can operate in both pit and non-submersible settings and are available with “Complete” or “Life Support/Trickle” shutoff options. The “Life Support/Trickle” setting allows a small amount of water to pass through the service, which is enough to drink but not enough to run appliances, sprinklers or showers. This option is ideal for utilities whose charter or local laws do not permit them to completely disconnect customer water services.

Leak detection relay

Dwyer Instruments has just released the new series DLD Dual Channel leak Detection Relay. The series is used to monitor the shaft seal of two submersible pumps to detect a leak before pump failure. A leak is detected by sensing the status of a float or conductivity switch installed in the seal cavity. When this resistance drops below the set sensitivity, the output relay energizes and the LED indicator illuminates. The DLD offers normally open relay contacts to energize an alarm and de-energize the pump in the event of a leak. When the seal failure condition clears, the relay automatically resets. Installation is made simple with the standard 8-pin octal mount. The DLD is available in two different sensitivities: 10 k to 25 k ohm adjustable and 4.7 k to 100 k ohm adjustable. All models utilize a 120 vAC control voltage.

The Ridgid® SeekTech® SR-60 utility locator provides end users with more information for easier and more accurate locates. The SR-60 is the only utility locator with the capability to receive the full range of locatable frequencies, allowing it to be used with any pre-set frequency transmitter. Expanding on the SR-20 utility locator, the new unit has additional frequencies and more versatility. Users can locate at the broad frequency range of 10 Hz to 490 kHz, and can tune the frequency 1 Hz at a time, allowing the locator to be used with any pre-set frequency transmitter. The unique passive search mode can be used to search all broadband passive frequencies at once, allowing for easy identification of unknown metallic lines in the target area. These features provide the necessary data for the professional locator to develop a comprehensive and accurate understanding of the underground infrastructure.
