Because it is like crystal liquid. You must use silica gel to replace. You must use it when you measure the flow rate. If you do not use the silica gel, it will have no signal - If you want other types transducers, please search it in our store ## Images ![TDS-100H-HS+HM Transit-Time Handheld Digital Ultrasonic Flow Meter for DN15-700mm Pipe Size with Bracket Transducers - Image 1](https://m.media-amazon.com/images/I/81YrJqsf-jL.jpg) ## Questions & Answers **Q: Our pipe size ranges from 1/2 inch to 4 inch and is pvc what is the price for a unit capable of this? what p/n do i need for this pipe size? is it good for pvc pipe** A: 1/2 inch pipe is too small, it is at least 15mm pipe. **Q: Does this item have any output jacks. Pulse? 20ma?** A: The meter has a communication interface that serves to recharge the batteries or connect to external media like a computer. Connectivity is compatible with Fuji flow meters. Don't know what you mean by "pulse" and "20ma". Specs on this meter are close to the Fuji. The tests we've done indicate that the TDS comes very close to actual flow rates through our water lines. Having used both this meter and the Fuji I would say that the TDS is slightly more difficult to set up, but once the operator learns the coding it is relatively simple. For the price, and after one month of use, my opinion is that it is worth every penny. **Q: Can this unit measure flow of 1 gpm** A: We set up a 2" PVC pipe 10' long with inlet meter & outlet valves so we could monitor flow and TDS readings. The unit was able to measure flow down to less than 1/4 gpm and up to the limit of the pipe. We rarely look for leaks smaller than 1GPM in the real world, but the machine will measure considerably less flow. **Q: is it a complete package, which includes flowmeter, two transducers and one or two brackets** A: Yes, it will contain flowmeter and HS, HM transducers with bracket. Also other accessories like tape, cable, clamp fixture... ## Customer Reviews ### ⭐⭐⭐⭐ Initially Impressed *by A***R on February 25, 2016* I work at a small water district and we have had need of an ultrasonic flow meter in the past to detect water leaks. We have used a Fuji flow meter available from an agency that helps small districts find water leaks. The Fuji meter is out of our price range at around $6000+, so when we found this meter we thought it was worth a shot. We made a test flow pipe with a water meter attached to the incoming end to monitor flow amount, and a variable discharge to control the flow at the downstream end.Once the TDS was set up and calibrated we checked the flow through the 2" line and it was almost exactly what the water meter indicated as flow amount, within .1 gallon per minute. The TDS meter was consistent for the one hour test and based on this initial performance we are pleased with the results. Although the hand held unit is less substantial than the Fuji it seems to have all of the same features. Set up was relatively strait forward once a few pieces of information were obtained (pipe sizing chart can be found online). The aluminum case and associated hardware that comes with the TDS seem to be of good quality. The only issue so far is that I get a "no signal received" when trying to use the small sensors (HS), but I think that is due to not keying in the correct information at set-up (reason I did not give it five stars). The HM sensors work perfectly thus far.We will be taking the meter out to the field for leak detection next week and will hopefully have the Fuji meter right along side to compare to. I suspect the readings will be comparable. For our purposes the amount of flow is secondary to actual flow detection since we are trying to isolate leak areas rather than monitor flow amount, but want the meter to be reasonably accurate so that we will know how much water is passing a given point in the line.I will post more on this instrument as we use it under actual real world conditions. So far, so good............. ### ⭐⭐ Bracket transducers are not convenient, difficult to mount and Chinese interface. *by D***D on February 15, 2019* I waste good time to trying to change the language from Chinese to English. The device is not very convenient to measure the flow because of the big bracket transducers as I could not mount them as indicated and get accurate results. Non bracket transducers are way better. The manual was in a mix of Chinese/English language. It was hard to understand it, finally I returned. ### ⭐⭐⭐⭐⭐ Five Stars *by J***N on February 23, 2017* AAA ## Frequently Bought Together - TDS-100H-HS+HM Transit-Time Handheld Digital Ultrasonic Flow Meter for DN15-700mm Pipe Size With Bracket Transducers - CGOLDENWALL 1.5 Inch Turbine Flow Meter LCD Digital Display Flowmeter with 1.5" Inlet/Outlet, Flowmeter for Diesel Kerosene Gasoline, Flow Rate Range 10-73.5 GPM - GRYVOZE 1 Inch Digital Turbine Fuel Flow Meter, 2.6-26 GPM Inline NPT Thread Flowmeter with 3/4 in Adapters for Water, Diesel, Gas Oil, Gasoline, and Other Liquids - Supports Gallon, QTS, PTS, L, m³ --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/1637951-tds-100h-hs-hm-transit-time-handheld-digital-ultrasonic-flow](https://www.desertcart.tn/products/1637951-tds-100h-hs-hm-transit-time-handheld-digital-ultrasonic-flow) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-04*
