Pulsar Stingray Portable Flow Meter Price and Sourcing for Urban Drainage Loggers
Quick Answer: A complete Pulsar Stingray portable flow meter for urban drainage logging is typically quoted from USD 3,000 to 7,000 ex works depending on velocity sensor, level range, cable length, and data output. Silver Automation Instruments supplies this class of portable area velocity loggers and clamp-on ultrasonic flow meters from China to Southeast Asia, Oceania, Latin America, Africa, and the Middle East. Send your channel width in mm, pipe diameter in DN, minimum and maximum level in m, and flow range in m3/h for a same-day price indication.
Most engineers skip this part and compare list price first. That is a mistake for urban drainage projects. A drainage logger does not work alone. The price changes fast when you add a pressure level sensor, a Doppler velocity probe, a 30 m cable, and an SD card logger. In practice, the final quote moves 40 to 60 percent above the base unit.
What the Pulsar Stingray Does in a Drainage Network
The Stingray is a portable area velocity flow meter. It logs level and velocity in partially filled pipes, stormwater culverts, and combined sewer overflows. Most units use a Doppler velocity sensor and a submerged pressure level sensor. The logger converts level and velocity to flow using channel shape and a roughness coefficient.
Users in Manila, Jakarta, and Lagos use this type of logger for rain event studies, inflow and infiltration checks, and pump station performance tests. A typical setup records at a 5 minute interval for 7 to 30 days. Battery life is often 30 to 90 days depending on logging rate. Some contractors download data with a USB cable. Others read data over Modbus RTU.
Budget Price Drivers for Pulsar Stingray Portable Flow Meter
For budget planning, a complete portable area velocity logger class is usually USD 3,000 to 7,000 ex works. A base unit with a 10 m level sensor, a Doppler velocity sensor, and an internal logger may sit near USD 4,500. Longer cables, ATEX Zone 1 approval, dual sensor inputs, or rain gauge inputs push the price higher.
Do not compare the Stingray price to a clamp-on transit time meter. Clamp-on meters measure full pipe flow. Urban drainage loggers measure open channel and partially filled pipe flow. The price structure is different because the sensor is submerged and must handle silt, debris, and variable velocity profiles.
Sourcing Urban Drainage Loggers from Silver Automation Instruments
Silver Automation Instruments supplies flow meters, level sensors, and paperless recorders for water and wastewater projects. We are based in China and export to over 40 countries. Our customers include drainage contractors, municipal water boards, and OEM skid builders in Southeast Asia, the Middle East, and Latin America.
Because the Pulsar Stingray is not always the best fit for every site, we often supply alternatives. For full pipe sections upstream of a drainage logger, we recommend our portable clamp-on ultrasonic flow meter for DN15 to DN1200 pipes. This meter uses clamp-on transducers, measures flow from 0.03 m/s to 12 m/s, and gives ±1 percent of reading. For open channel applications, we supply ultrasonic level transmitters with 4-20 mA HART output and a built-in flow totalizer. We can also pair a logger with our paperless recorder for pump station monitoring.
If you already have a Pulsar Stingray quotation, send it to us. We check the sensor range, cable length, logging interval, and export terms. In many cases we can propose a similar urban drainage logger with a shorter lead time or better landed cost for Indonesia, Vietnam, Saudi Arabia, Brazil, or Nigeria.

Common Site Conditions That Change Price
We have seen this on customer sites many times. A city drainage engineer asks for a low price. Then site conditions arrive. The channel is a DN400 concrete pipe with 200 mm of silt at the invert. The flow goes from 0.05 m/s at night to 2.8 m/s during a storm. The level sensor needs a 10 m range, not 5 m. The logger needs a 50 m cable because the manhole is deep.
These conditions change the price. For urban drainage logging, budget for a velocity sensor that works from 0.03 m/s, an IP68 enclosure, and a pressure level sensor that tolerates occasional surcharge. Do not use a level-only logger if the municipality needs flow in m3/h for regulatory reports.
Temperature also matters. In the Middle East, a manhole logger can see 60 °C inside the enclosure in summer. Battery life drops. In Latin America during the rainy season, humidity and condensation kill unsealed connectors. We usually recommend an IP68 logger with desiccant packs and a sealed battery compartment.
How to Get a Quote from Silver Automation Instruments
Send us the following data for a price indication and model selection: channel width in mm, pipe diameter in DN, minimum and maximum level in m, expected velocity in m/s, flow range in m3/h or L/s, power supply, and data interface. Also tell us the country and port of destination. We quote EXW, FOB, CIF, or DAP terms.

FAQ on Pulsar Stingray Portable Flow Meter Price and Urban Drainage Loggers
Q: What is the actual price of a Pulsar Stingray portable flow meter?
Most complete kits for urban drainage logging are quoted from USD 3,000 to 7,000 ex works. The final price depends on level sensor range, velocity sensor cable length, data output, and hazardous area approval.
Q: Can Silver Automation Instruments supply a replacement for the Pulsar Stingray?
Yes. We supply portable clamp-on ultrasonic flow meters for full pipes and ultrasonic level transmitters for open channels. We also supply paperless recorders. Send your pipe diameter in DN and flow range in m3/h, and we will propose a compatible logger set.
Q: How often should an urban drainage logger record data?
Most drainage studies use a 1 to 15 minute logging interval. For short rain events, use 1 minute. For long term inflow and infiltration studies, use 5 or 10 minute intervals to save battery and memory. We recommend you test one rain event at 1 minute before starting a 30 day survey.
Q: Can this logger measure partially filled pipes and open channels?
Yes. This class measures level and velocity in partially filled pipes, culverts, and open channels. It is not the same as a full pipe electromagnetic flow meter. Select a logger with a Doppler velocity sensor and a pressure level sensor for these applications.
Q: What pipe sizes can Silver Automation Instruments cover?
Our clamp-on ultrasonic flow meters cover DN15 to DN1200 standard. For larger pipe sizes, we offer a high temperature clamp-on sensor set. For open channels, our ultrasonic level transmitters typically measure up to 10 m or 15 m depending on the transducer. Tell us the channel width and maximum level in m for a specific model.
