Restmo Smart Water Flow Meter Outdoor Irrigation Bluetooth Programming Manuals
Quick Answer: The Restmo smart water flow meter manual covers Bluetooth pairing, K-factor entry, pipe size selection, unit setup, and pulse output for outdoor irrigation. This guide explains the setup sequence used for sprinkler, drip, and tank fill systems. For larger irrigation lines, Silver Instruments offers electromagnetic and ultrasonic flow meters with 4-20 mA, pulse, and RS485 Modbus outputs.
What the Restmo Bluetooth Programming Manual Covers
Users usually start with the Restmo mobile app. Pair the meter with the phone. Then select pipe size in inches or mm. Enter the K-factor from the sensor tag. Set the flow unit to L/min, m3/h, or GPM. For outdoor irrigation, most users set m3/h for main lines and L/min for zone valves.
The manual also covers totalizer reset. In practice, a farm manager in Queensland may reset the totalizer after each irrigation cycle. That helps track water use per block. The pulse output setup matters when you connect the meter to a controller or remote monitoring unit. Restmo meters often send one pulse per liter or one pulse per 10 liters. Check the controller input before you set this value.
Common Outdoor Irrigation Programming Sequence
Most engineers skip the default settings and start with the pipe ID. A DN40 PVC pipe is not exactly 40 mm inside. Use the actual inner diameter from the pipe schedule. This reduces totalizer error. Then check the K-factor. The K-factor is printed on the flow sensor or in the calibration sheet. Enter it exactly. Do not swap meters without updating the K-factor.
After that, set the over-range alarm. For drip irrigation, the flow rate can drop to 100 L/h. A 2 inch meter may not read that low. In that case, use a smaller meter for each zone or install a bypass. We have seen this on citrus farms in South Africa where one main meter cannot track low flow from a small night irrigation block.
Where Restmo Style Meters Fall Short in Large Irrigation Projects
Restmo style meters are fine for small PVC lines. They may be rated for 10 bar. But large pump stations, fertilizer injection lines, and sand filters often run at 6 to 10 bar with high solids. The plastic body can crack under water hammer. Some users in Vietnam reported that a sudden pump stop caused a pressure spike that damaged the meter body.
For those jobs, an electromagnetic flow meter from Silver Instruments is a better fit. It has no moving parts. It handles wastewater, sludge, and water with fertilizer salts. The signal output is 4-20 mA plus pulse. You can add RS485 Modbus RTU. This works with common irrigation controllers and SCADA systems.
Silver Instruments Options for Irrigation and Water Distribution

An ultrasonic clamp-on flow meter is also available. It can be installed without cutting the pipe. That helps when the system is already running or the pipe is buried. A customer in Saudi Arabia used a clamp-on meter on a 6 inch HDPE line to verify the main pump output. The reading matched the pump curve within 2 percent.
Output and Programming on Silver Instruments Flow Meters
You can set the pulse output from the meter keypad or via Modbus. Common values are 0.1 L per pulse, 1 L per pulse, or 10 L per pulse. Match this to the irrigation controller input frequency. If the controller max is 100 Hz, do not set 0.1 L per pulse on a 50 m3/h line. The output will exceed the controller limit.
The 4-20 mA output can be scaled to the flow range. For a DN80 meter, a typical range is 0 to 100 m3/h. The meter also stores total flow in a nonvolatile register. It keeps the totalizer during power loss. This matters on solar powered irrigation skids where the power cycles every morning.
FAQ
Can I use the Restmo app with a Silver Instruments meter? No. Silver Instruments meters with Bluetooth use a different app. For most industrial jobs, we recommend RS485 Modbus or 4-20 mA instead of Bluetooth. The signal is more stable over long cable runs.
What pipe sizes suit electromagnetic meters for irrigation? DN15 to DN300. For small drip zones, DN15 or DN20 works. For main lines, DN50 to DN150 is common. Tell us the pipe material and inner diameter.
Does Silver Instruments supply battery powered water meters for remote sites? Yes. Some electromagnetic meters can run on a 12 V or 24 V DC battery with a solar panel. Battery life depends on the sensor and output settings. A 12 V 40 Ah battery typically lasts 3 to 5 days without solar input.
Which flow meter is better for fertigation lines? Use an electromagnetic flow meter with PTFE liner and Hastelloy C electrodes. This handles acidic and saline liquids better than plastic body meters.
Can the meter send data to a mobile phone? Yes. We can add a Bluetooth module or a LoRa gateway. For short range setup, Bluetooth works. For a large farm, LoRa or 4G is better. Ask us for a wireless option based on your site map.
