Key Takeaways
- A hydrant-flow MMS is hydrant ID and pitot/GPM crop — not a still of the whole intersection.
- Water utility NOC and fire company are different lists. Do not reuse a load-bank template.
- Free is 1 device, 300 SMS lifetime, and 300 contacts. Developer is 25,000 SMS per year. Platform price is devices plus send volume.
- Crew-app OTP stays off the flow radio.
- Idempotency is hydrant-id plus ticket — a failed pitot recuts the same work order.
Summary
Scenario 1761 is field-service MMS for fire-hydrant flow tests — not generator load-banks, not fire-pump weekly indoor, not streetlight photocells, not water-tower hatches. Cap-off is a hint. Pitot GPM crop is the join. Service pricing is devices plus SMS send volume. You bring the phones and operator credit. Free is 1 device, 300 SMS lifetime, and 300 contacts.
Starter allows 2 devices: flow dual-SIM plus a spare. Uncapped platform volume is not unlimited carrier SMS. Confirm payloads in Developer Center.

hydrant + ticket — failed pitot recuts once
A hydrant crop is not a street dump
Shop copy names the hydrant and pitot reading. 311 alerts live elsewhere. Mixing them is how a technician STOPs the week the only barrel they own is actually in spec.
If dispatch fires “complete” when the cap comes off, the shop thinks the GPM is photographed. Join pitot crop. Suppress cap-off-to-buyer templates.
Hydrant-flow MMS matrix
| Event | SMS / MMS | Failure |
|---|---|---|
| Cap-off | None or “on test” | “Complete” before pitot crop |
| Pitot crop | Hydrant ID + GPM | 311 stuffed in |
| Failed pitot retest | Once after new crop | Two complete texts |
| Crew OTP | Auth pool | OTP on the flow radio |
GPM crop vs cap-off
Persist hydrant-id plus ticket. DLR. MCP wraps REST only.
Lane closure is not auto-reply
The MMS is that hydrant. A street notice is marketing. FTC business guidance is not a reason to hide the crop behind a city-wide wet-street blast.
Devices, volume, and airtime
Flush seasons spike. We meter devices and platform sends. Free (1/300/300) is one barrel proof.
Flow operations
Charge the flow chassis before first cap. Setup, Downloads, pricing.
Decision guide
Ship when notice joins pitot crop. Delay if cap-off texts “complete.” Not a CodeCanyon water-utility pack.
Hydrant checklist
- Hydrant plus ticket idempotency.
- Cap-off silent as complete.
- 311 off shop purpose.
- OTP off flow SIM.
- Developer Center fields confirmed.
