Aquify Flow Meter: Smart Residential Main Line Telemetry Shutoff Systems
Quick Answer: Silver Automation Instruments supplies flow meters for Aquify Flow Meter: Smart Residential Main Line Telemetry Shutoff Systems projects. The right meter for most buildings is a DN15 to DN50 electromagnetic or ultrasonic meter with pulse plus 4 to 20 mA HART output. Send pipe size, pressure in bar, temperature in °C, and normal flow range to get a quote for a new build or retrofit.
What Is a Smart Residential Main Line Shutoff System
A residential main line shutoff system measures flow and pressure at the building entry point. If flow stays above a leak threshold or pressure drops too fast, the controller closes a motorized ball valve or butterfly valve. The system uses a flow meter for real data, not a simple dry contact float switch. Flow data matters for apartment buildings and large houses where a hidden pipe break can flood basements or common areas.
Why Aquify Flow Meter Data Drives Shutoff Logic
The controller needs clean data to separate normal use from leaks. A meter with 0.5% of reading accuracy works better than a mechanical paddle wheel. The flow meter sends a pulse for every 1 litre or 10 litres. The PLC or RTU compares the pulse count to a rolling 30 minute baseline. If flow exceeds 12 L/min at 03:00 for 20 minutes, the controller triggers a valve closure and sends an alarm through 4G LTE. Most engineers skip the baseline learning step and then get false trips from toilet fill cycles. Use a minimum flow cutoff at 1.5 L/min to avoid nuisance alarms.
Silver Instruments Flow Meter Options for Aquify Type Panels
Silver Automation Instruments supplies electromagnetic flow meters and ultrasonic flow meters for residential and light commercial water lines. Sizes cover DN15, DN20, DN25, DN32, DN40, and DN50. Wetted parts use PTFE or EPDM liners with 316L stainless steel electrodes. Outputs include pulse, 4 to 20 mA HART, and RS485 Modbus RTU. Power options are 24 V DC from a panel supply or battery powered for sites without AC. Model pairing: Silver Instruments DN25 electromagnetic flow meter with 316L electrodes, PTFE liner, pulse plus 4 to 20 mA HART output. In practice, a DN25 electromagnetic meter with 0.5% accuracy and IP68 sensor body handles most single building entry points up to 10 m3/h.
Telemetry and Shutoff Valve Integration
The flow meter output connects to an RTU, PLC, or Aquify type telemetry node. A typical panel sends data over 4G LTE or narrowband IoT to a cloud dashboard. The shutoff valve uses a 12 V DC or 24 V DC actuator with a 5 to 10 second open or close time. Because the valve is downstream of the meter, the controller can verify closure by watching flow drop to zero. If the flow does not drop below 0.5 L/min within 15 seconds, the system sends a second alarm. The second alarm confirms the valve actually seated and did not jam.

How to Specify an Aquify Flow Meter Quote
Send us the following data: pipe size in DN, working pressure in bar, fluid temperature in °C, normal flow range in L/min or m3/h, maximum flow in m3/h, output signal preference, and power supply. For new builds, include the controller type and whether the valve is 12 V DC or 24 V DC. For retrofits, include existing wiring photos and straight pipe length before and after the meter. We normally recommend 5 DN upstream and 3 DN downstream straight pipe for electromagnetic meters. Our team will match a Silver Instruments meter with a suitable calibration certificate and manual in English or Spanish.

FAQ
Question 1: What flow meter works best for an Aquify Flow Meter: Smart Residential Main Line Telemetry Shutoff Systems project?
Answer: A DN15 to DN50 electromagnetic flow meter works best for clean water lines. Use a clamp on ultrasonic meter only if pipe cutting is not possible. Both should have pulse and 4 to 20 mA HART output.
Question 2: Can the Silver Instruments flow meter trigger a valve directly?
Answer: Most meters do not close a valve directly. The meter sends a flow signal to a controller or RTU. The controller then sends a close command to the motorized valve. Some panel versions accept a high flow relay output for direct valve wiring.
Question 3: What accuracy is needed for leak detection?
Answer: A meter with 0.5% of reading accuracy or better for electromagnetic types gives reliable low flow detection. Avoid mechanical paddle wheel meters below 2 L/min because they often under report flow.
Question 4: Do you supply battery powered meters for remote telemetry sites?
Answer: Yes. Silver Automation Instruments offers battery powered electromagnetic flow meters for DN15 to DN50 lines. Battery powered meters work for sites without AC power and can run 3 to 6 years depending on sampling interval.
Question 5: How do I get a quote for an Aquify flow meter system?
Answer: Send pipe size in DN, pressure in bar, temperature in °C, flow range, output signal, and power supply to our team. Contact Silver Automation Instruments at Tel +86-135-1213-1526 or WhatsApp 86-135-12131526. Our WeChat is +86 13512131526.
