Hi, I need a SMS flowmeter in a water resistant plastic box. The device is to be used in water treatment applications where the water treatment filter needs to be serviced when a certain amount of water passed through the water filter, which means that the capacity of the water treatment filter is exhausted and therefore needs to be exchanged or regenerated. My idea was to have an flowmeter mounted on the inlet valve of the water filter, and then pulse the SMS device every time one liter has passed. Via dipswitches, the technician then defines the capacity of the filter eg. 3000 liters, and when the flowmeter has pulsed 3000 times, it sends an SMS to a central sms gateway. The end result most be a XML file for import to our service management system. Because of corrosion risks, the flowmeter needs to be in either stainless steel or plastic. The SMS device must also be in a water prove box as there are high risks of water exposure. The smart thing would be to power the box by rechargeable batteries, and use the power from the flowmeter via a little mill to charge the battery. This is for high scale with 1000+ devices, so low expenses is key. Max price for 1 complete device with flowmeter is 50$. Remember, this is for industrial use, so it must be working - always.

I have BS, MS and PhD degrees in Electrical and Electronics Engineering from one of the most reputable universities in Turkey and have 15 years of analog and microcontroller based systems design experience (both hardware and firmware) and 5 years of RF design experience. I am founder and manager of an R&D company focusing on analog and embedded systems design. We have a design idea involving an enclosed generator so that leakage is not possible. Please note that the bid is for prototyping, as such: - The plastic casing will be 3D printed or CNC machined in our desktop 3-axis CNC. 3D CAD files for the case will be provided but case molding design is not included in the bid, it will be performed for mass-production stage at an extra cost, if wanted. - FCC/CE certifications are not included since even only independent laboratory testing costs exceed this bid. Some manufacturers skip these tests and self-declare conformity but this poses risks in the market. We can work on certification costs and process before mass production. Alternatively, if you find it suitable, we can declare CE conformity after performing main tests in-house; this will minimize certification costs. - Flow-meter readings will be calibrated using a commonly available registered flowmeter. Any related certification is not included in the bid. -the requested prepayment is only for zeroing immediately taken site commission. We found it necessary because of employers who disappear after awarding.

Hej, vi tager den lige på dansk :) Da jeg har en større erfaring med GSM og sensorsystemer vil jeg glædeligt byde på dette projekt. Jeg har gennem de sidste 3 år arbejdet med medicinske GSM basserede systemer, hvis krav er meget strenge når det kommer til funktionalitet og sikkerhed. Her mener jeg at jeg kan tilbyde noget unikt. Jeg har erfaring med flere typer af GSM systemer, samt en god aftale med en M2M teleoperatør således at SMS håndtering kan klares nemt. Samt tilbyder jeg også muligheden for at benytte embedded SIM's således at man opnår en højere pålidelighed. Du ønsker en enhedspris på ca. 300kr, dette kan godt opnås, men er lige på grænsen. Derfor kræver det en større indsigt i produktionsmetoderne, der har jeg større erfaring ifølge mit eget produkt, og et stærkt samarbejde med flere danske og polske produktionsvirksomheder. Prisen er mulig at forhandle da produktets virkemåde ikke er helt fastlåst, og kan muligvis simplificeres. Derfor vil jeg med glæde tage det over en personlig snak. Du er velkommen til at kontakte mig via denne side, eller direkte på 26504404. Mvh Nikolaj Kjær Nielsen
